I'm fairly certain that the OP was not interested in hearing why the SSPX thinks the new rites are valid.

My point is that the Resistance has no right to criticize the SSPX on this point( given that the Society’s position on this comes from a now Resistance Dominican)

That's not valid logic.  Those in the Resistance have every right to disagree with those conclusions, regardless of who made them.

No they don’t. The Avrille Dominicans are talked up on here as the intellectual powerhouse of the Resistance. By disagreeing with Fr. Marie, Resistance faithful are saying they know better than he does on this. In that case, they should criticize him( not just the SSPX) as he came up with the position. They should also leave the Resistance and start a new, purer movement ( as they know more than one of their brightest priests)
Fr. Marie is probably one of the seminary professors training Resistance seminarians. If Resistance faithful don’t trust him, who do they trust?

Maybe some do?  Until the Church decides, it's his opinion vs other's opinion.

That's a fair point.  My criticism is why did the new-sspx veer from +Tissier's position?  And to your point, why did the Resistance veer from him as well?  It's still opinion vs opinion, but I see no "new information" that necessitates a change from +Tissier's strong doubt.

That's just silly.

My last point was a jab. I’m just emphasizing the point that this man is training Resistance seminarians( your future priests) If you want people to leave the SSPX over things like this( which some Resistance faithful seem to) then leave the Resistance as well

I've been going exclusively to SSPX chapels since I came back to the Church 25 years ago. The SSPX as an organization from the beginning has always taught that people in any religion can be saved, which I do not agree with. The SSPX also grants annulments, which I do not agree with. The SSPX is basically just a coop of priests, what the SSPX teaches as an organization and what the individual priests believe is another story. Resistance people here disagree with Bp. Williamson on some points. Your logic only has traction with people who blindly follow groups. Do you think the way you do because you blindly follow groups? 

I do not follow groups, I follow truth, which is the most important thing, specially today, when the shepherd is struck and the sheep are scattered. No group is 100% correct today. When we have a real pope, then we will have the source of truth to clarify all of these questions and doubts.

By "position", do you mean a private note bishop Tissier wrote in response to being given a Coomaraswamy book and "having read it rapidly"? And wasn't that before the Avrille analysis?

Then we are no better than Protestants. Yes, one may disagree with the their Trad priest/Society on minor points( one may hold to theistic evolutionists even though their priest is a creationist), but if you’ve gotten to the point where you think your priest is flat wrong about something like the validity of a Rite, you ought to find another place to go.
Disagree with the SSPX on this? Fine, go to the SSPV( who view the New Rites as doubtful ) or if you want to remain at your SSPX chapel, don’t mouth off about how you disagree with your priest and the Society on the internet( just keep it to yourself) Not directed at you Lad- just making a broader point.

Catholics have regularly disagreed on various points of doctrine throughout history.  We owe assent ultimately only to the Magisterium, not to individual bishops or priests who lack jurisdiction or teaching authority.  Someone could be mostly aligned with the Resistance and yet disagree with something that one of the Resistance bishops says or believes.  To say that this is Protestantism, I don't even know what to say to that.

So I must break communion with an entire group because I don't agree with one or two points that are not de fide and which Catholics in good faith are entitled to disagree about?
