It's not that the entire spectrum is further right, it's more that the vast majority of society is dealing with actual praxis and thus living in some anarchocapitalist hellscape where fairly centre-liberal reforms are a big lurch left, while a small pocket of cosplayers are online pretending they're about to start the February Revolution.

It's not a one axis thing, either. Americans are also blissfully unaware of how hostile European leftism is against some of their cultural causes. We don't talk enough about how it's well accepted among Euro leftist circles that surrogate pregnancies are a form of human trafficking, or that all sex work should be banned. Culture is culture, left/right positions aren't universal.
