Dominic, I will share something I just learned, having been here just slightly longer than you. (But I have been working very hard to get the lay of the land, because I want to know if this is a benign place, or not. I am learning!)

You should know that you are not allowed to use the "like" and "dislike" buttons. Only regular (not newcomer) members can use those buttons. They are the (swarm of) judges, and you, the newcomer, are here to be judged. You heretic.  

In my first good insider look here at SSPX and SSPX-related groups (I thought it was "Trad Cath" but now inside, I think unless I am in some ways related to SSPX I am in fact a disdained outsider to a chunk of folk here), I am beginning to get the idea that this is an insiders group that probably judges each other quite a bit.  Members of this group of elites, who are so much better than us, work to keep each other toeing the line. That certainly works to feel a bit like being constantly battered to many for these elitists, who must work tirelessly to adjust and align their life so they can avoid being judged for doing it wrong. This is all very tiring. But a newbie showing up here is a delightful opportunity to turn it around and enjoy being the smug batterer, rather than the battered!  That explains the "sharkbait" feeling I got right off.




If you aren't already an insider, then you just aren't good enough. And you being "ignorant you" means that you have nothing to offer. Just a lot to criticize (and dislike).

(There are nice folks here too, and I am thankful. I would like to know these like-minded, sincere Catholics better, but I am beginning to doubt I can handle exposing myself to the very real element of ugliness and unkindness, whatever size it is, that is deeply rooted and at home here. And I just cannot understand how exposure to such a beautiful Mass would not transform people to be more Christlike. How?)  

I hope that you stick around, Eliza. You seem to think that you already know it all (I'm like that too), but that approach isn't going to work well here. There's a lot you can learn here, if you decide to develop a thicker skin. The Catholic Faith isn't all about peace and love, as you have perhaps been led to believe.

Perhaps you should try to understand why you have downvotes. I know why I have a lot of them, but it's okay. I don't mind. 

"Meeting someone where they are" can mean a lot of different things. I'd ask for clarification if unsure.

I mean Paul IN ONE SENSE did so with the Athenians.

Francis is bad because he strains Pelagian and acts like "good people go to heaven"

I agree that it can mean different things, but to Pope Francis, and often with Novus Ordo Catholics, it often means that we accept and are okay with whatever "lifestyle" they are attuned to, and we overlook any problems such as co-habitation, homosexuality, etc, in hopes that maybe someday, they will be okay with what the Church actually teaches and insists on (or used to insist on).

Pope Francis is very much into the "meeting someone where they are," which coincides with "accompaniment." The problem with that view is that there is not a clear teaching given to those whom are "met where they are," because it might, for example, cause them to turn away from conversion. But that's a BIG problem, because they absolutely need to know what proper Church teaching is, even if there's a chance that they might reject it and not convert. It may be inconvenient to live as Our Lord expects us to, but that doesn't mean we shouldn't do it.

Some of the Apostles themselves were not happy when Our Lord said that divorce and remarriage is not allowed. But that did not stop Our Lord from proclaiming the truth.

That looks very fishy.

As you can see, "(faith)" is included in the original.

What in blazes are you talking about?  Those of the Old Testament who went to the Limbo of the Just were justified by the Jewish Faith!  They were justified by the rite of circumcision and by the sacrifices of the old law, which were still in effect until Pentacost.
.You have no idea what you're talking about.  You can't use a Church council's explanation of the New Testament laws to understand the Old Law.
.Abraham, Moses, Isaac, Jacob, Joseph, and all the prophets, etc, etc were "under the power of the devil"?  You're nuttier than squirrel turds.

Hold on there. I know some theologians teach that - maybe even St. Thomas - but it contradicts Romans, Galatians, Hebrews (regarding the old sacrifices which didn't justify from sin), and the Magisterium of the Church. I'll find the quote from Denzinger, but I'm pretty sure that one of the popes quoted in there said circumcision didn't justify. 

This is what you wrote in the OP:  Did you ever find out about the first teacher who took your child into the hallway?  Did this really happen?  If not, then it sounds like your child may have made a blatant lie.  If not, I still wonder whether the truth lies somewhere between what your kids said and what the school is saying.

One teacher removed my child from class to speak with him in the hallway about how good and important it is to make the responses, and another teacher told my other child’s class that whoever made the responses would receive two marbles (my child perceived that this was in response to this teachers’ having discovered that he was not making the responses).

Well, later that story changed from one teacher taking one of my sons out into the hall, to another teacher taking my other son out into the hall.  Then later after continuing my questioning, it turned into “maybe the teacher took me into the hall about something else.” 
So...
But here is another weird aspect I am trying to figure out:
Apparently, my spouse and mother, unbeknownst to me, were saying a Novena to help decide whether the kids should go to the school.  The kids told us this info on day 7 of the Novena, and we immediately made the decision (my spouse later informing me of the Novena, which sealed the deal for me).  Day 9 was the school registration deadline, and because of the curious timing of the “revelations” from our children, the Novena in play, and the “coincidence” of the Novena ending on the registration deadline (combined with the fact that my spouse was suddenly willing to homeschool because of the whole episode, which was not at all their position before this all happened), we thought heaven had answered my spouses prayers, and were at peace with it all.
Now, learning after the fact that it is extremely unlikely our children accurately recounted the matter to us, I am wondering whether heaven had spoken after all.
Could/would Our Lady use mistakes or lies to get us to come to this decision?  That seems blasphemous.  On the other hand, could heaven make good (ie., the decision) come from evil?  I think that answer is yes.
Meanwhile, there are other major things happening in our life, which I will not go into, but I have perceived/wondered/felt that something I am about to do has aroused either the anger of heaven or hell (the latter, I think/Hope), and that this incident is a consequence of my future action, though I could be wrong about that:
Did the devil trick us into making this decision, or did heaven respond, or neither?
All I can say is that I have been relieved I will not have to worry about the kids at the school, and had a great feeling of peace after making the decision, even though this subsequent revelation of inaccuracies somewhat muddies those waters.
I wanted them out anyway, so maybe the peace was purely natural, and not the inspiration of the good angel (or, maybe it is the disturbance of soul caused by the devil who wants me to second guess myself which has muddied the waters).  Both possibilities are discussed in the discernment of spirits.
In any case, the rules also say never to make a decision in a state of turmoil.
Consequently, we will, for now, live with the decision and carry on.
