I'm feeling like either you didn't read the posts I shared, or you simply had a different takeaway than I did. I'll assume the latter rather than the former.
The way I read it, the mass "feel good protests" serve a societal purpose to give those willing to take stronger actions permission to do so. I'm not suggesting violence, but peaceful protests that actively impede MAGA from doing the things they're currently getting away with doing.
For example, standing in opposition to entrances to courtrooms or prisons were immigrants might be unjustly imprisoned. If more people simply become "dead weight" in these situations (making it difficult for police to arrest and remove them), it makes it more difficult for MAGA to keep doing what they're doing, forcing change out of their own need just to remove the impediments (someone pointed out in that thread, for example, that in all protests yesterday, the protestors outnumbered the police, so we're making the point that MAGA simply can't physically force their way through the way they'd like to).
Not everyone can afford to allow themselves to be imprisoned (for example) to protest injustice, but the more people who feel that they can, the more likely the protests can reach a level where MAGA is forced to respond in new, more productive ways.
