There’s a very common mental trapping in humans where, once you’ve identified a serious problem or antagonist, you immediately become more sympathetic to its opposites or declared rivals. A lot of them had a genuine, valid concern with a capitalist society that was screwing them over, turned that into an identity, and ended up in echo chambers where that fallacy wouldn’t be called out. It’s difficult to get them out of there because they feel like they have to defend their identity and their social group, so in the rare cases where they meet someone who does understand and share their valid anti-capitalist positions but is capable of reasonably calling out their campist bullshit, they immediately jump to think it’s just “another lib” and refuse to engage.
