The follow-up question to demonstrate this point would be "would an American who identifies as radically left-leaning join a European conservative right-wing party if they moved to Europe?"
The actually difference in beliefs between Joe Biden and Mitch McConnell is paper thin.
Cultural Marxism is not a thing, please educate yourself beyond the videos of the lobster psychologist. You claim the left is 'radicalized' in a right-wing country where the right-wing party literally tried to undermine democracy through an insurrection less then a year ago...
And somehow the narrative is about the non-existent 'radicalized left' doing stuff and cultural Marxists trying to change our pronouns. It just feels sad to hear.
Who cares? The US is not a European country, so the point is irrelevant. And although I see it repeated a lot, I don't think it's factual either.
