To be honest what you say is not my experience, what instances have you been browsing? There are a few tankie instances but nobody likes them, if you've been there I understand you.
I feel the users are very similar to Reddits, probably the 99% of users migrated from there for the reason that reddit sucks significantly much more than before and it is the same reason you are here too.
We are all defeated by the current events and nobody who isn't braindead wants WW3. Give it time, more users will migrate and with it more diversity. The community is growing so be the change you want to see.
Isn't the CEO of Mercadona financing the far right in Spain Vox party? Did you wonder why Mercadona only hires spanish people, only to treat them like shit later anyway?

Man, fuck Mercadona.
