I think you're seeing backlash against being involuntarily exposed to (and often pushed to see) unbridled and deranged hatred and fear on traditional socmedia.

A conservative opinion like "I'm not sure communism is practical" is something that can be engaged with pretty cordially, "I think that education should focus on marketable skills" is an opinion I think is pretty misinformed but it's not something that exhausts me.

Unfortunately a lot of online conservatism is stuff like "I think there's a conspiracy by $minority to mind control us with vaccines" or "Should we be trying to make queer people afraid?" which aren't positions you can engage with.
