I'm starting to question that idea too. It seems like, just as often, these supportive environments on the web like to spiral down into an attitude of "ONLY this group supports and likes you; the rest of the world is hostile to you. Literal Nazis lurk outside your door ready to murder you. Better just keep posting online, and be sure to warn any new members about the Nazis outside their doors."
as far as I can tell this seems to be a very US thing, through somewhat exported from there through YT/TickTock/etc. (especially to other English speaking countries)
similar to this "over the top social justice" I'm mainly seeing in the US
honestly I have no idea what is going on with the US but it looks really really unhealthy and dangerous not just for the US (not just the points above but also many other points, like religious extremism, or the distribution of fascistic mindsets (but not Nazis) and others)
