I know the quote. The point the commenter was making is that the people who always chant it (i.e., 2A folks) were, in the end, the ones who stormed the Capitol at the behest of their favorite dictator.
You don't know that the commenter is chilling on a pile of wealth. He might be a sysadmin and got a job at some startup in Estonia for all you know. Try not making uncharitable assumptions about people while preaching from your high martyrdom horse.
Whether or not you can make a difference by standing your ground and showing a little solidarity
Solidarity isn't unilateral, and unless you're lucky enough to live somewhere where that actually exists among your neighbors, then no exertion of willpower on your part will make it happen. And yeah, standing your ground alone is suicidal.
I'm stuck here and can't help resenting someone who's clearly got the resources to help for bailing
That sucks, I'm stuck here too, but I don't resent people who get out while they can, because if I could I would too. Your resentment is your problem, not theirs.
If you can't see any virtue bravery or solidarity in the people who helped one another survive ghettos and concentration camps, the people who smuggled those actually in danger to freedom, or the people who formed literal armed resistance movements
That's a misreading of what I said. When did I say that? I said the people demanding that others stay did more harm to anyone foolish enough to listen to them. Bringing a few dozen extra neighbors to the camps with them wouldn't save anybody. Are we crabs in a bucket?
Which one of those things are you doing, by the way? Are you helping anyone survive? Are you smuggling anyone to freedom? Are you forming an armed resistance? And if the other commenter stayed, do you think they'd be in any position to do those things either?
Or is all you're doing demanding that people stay and keep themselves in danger? If I offered to let you climb over me to escape the bucket, wouldn't you take me up on it? Would you remain behind just to keep pulling others down when they try to climb out?
