What does excommunicated even mean in the current context?

The Church's power comes from God.  It is not a Genie in a lamp who obeys anyone who picks up and rubs the lamp.

Clearly Arch. Lefebvre didn't deserve to be excommunicated according to any sort of logic, rationality or historical consistency.   He was the ONLY Bishop in the world actually defending what the Church was for hundreds of years before.  If the Church can change to ignore previous teachings, reverse others and completely change its mission - then for hundreds of years before it was lying when it said it could not do that.

It's no disgrace to be sent to jail for crimes against the state in North Korea.  It is a badge of honor, because the state only sends good people to jail for that crime.

I've never understood why anyone would care about being "excommunicated" by and from a bunch of paedophile protecting sodomites.  And that is what they were.  That is not a disgrace, it is an honour.

And what value is being in communion with them when they are in communion with just about everyone else?  Pagans get to put their false gods on church altars and you are "excommunicated" from that.  So what?  Why would I care? 

If I die and Hans Kung, JP2 and Hans Urs von Balthasar are in Heaven I will WANT to be sent to Hell.  Because I will consider God to be a complete patsy and want nothing to do with him.

I absolutely detest men of their nature and certainly don't want to spend eternity in their company.

.  .  .  Resisting the current SSPX trend to de-demonize Vatican II is the right thing to do, even if no one else is doing it.  .  .  .  Vatican II was not about the Mass. It was never about the Mass. It was about the FAITH.  .  .  .  

Marcel Lefebvre in his 1974 declaration said, as an opening statement: ".  .  .  We hold firmly .  .  .  to Catholic Rome .  .  .  We refuse on the other hand .  .  .  to follow the Rome of Neo-Modernist and Neo-Protestant tendencies .  .  .  ".  Why demonize Vatican II? Modernist errors condemned should be sufficient.  I believe that ggreg and his words, regarding children and what they remember, as well as a sustainable example provided to his children, should likely be given deeper consideration.  The preliminary work to Vatican II went into the waste-bin, whatever Vatican II is about is only apparent after the fact of its closing.  Let's not go so far beneath ourselves as Catholic faithful obliged to learn our faith, only to condemn it for the lesson we didn't pass.

??  Errors and heresies are from the devil himself.  To condemn V2 is to demonize it as well.  Same thing.

Could you explain further?

Vatican II is not an error, but there is much in it worth learning, if you have a chance to again read Marcel Lefebvre's 1974 declaration his opening statements are very clear.  I think that's where the lessons are to be found in part.  

To protect the fool from his folly is to fill the world with fools.  No one is stopping you from drinking the V2 kool-aid.

I would say the status of the resistance in 2019 is slowly deteriorating and dying, Dont see any  progress or hope for them.

Bishop Zendajas announced last Sunday the SAJM long term goals of having a U.S. based seminary, U.S. based convent and regular church buildings for the three main SAJM chapels in the USA.

R&R people have a long history of not wanting to declare themselves as SV, (though try to find a portrait of the current Pope on their wall at home and you will be looking for a very long time).  Practically speaking I see little difference.  I certainly don't see SVs as bad and would probably be one myself if there was a decent SV chapel around my area.

That's because R&R people are, essentially, privationists (sedeprivationism), but they don't want to admit it or they don't understand the concept of privationism. You can manifest something while not understand the concept of it.
