To deny the reality that conditions in the US are continuing to push more young men towards fascism, and the necessity of having real material solutions to the root cause of that rightward shift, is to refute the working class revolution's ability to meet the needs of all oppressed peoples - and we are all oppressed under capitalism.
Personally, I'm interested in exploring the idea of a culture that rewards and incentivises militant direct action (executing the owning class) as a method for disaffected people to find community and solidarity among their peers.
How is it "US defaultism" when this is specifically about US events? It's fine if you have a dislike for the US and/or Americans, but this is going to an irrational level.
