"This is not how politics work in the rest of the world." A lot of the debate around Brexit in the UK worked exactly that way - on both sides.
I feel that's disingenuous. It wasn't the same way on both sides. This kind of false equivalence crops up in a lot of places but it needs to be called out. Many high profile Remainers claimed Leavers were/are racist, ignorant, far-right, small minded, hated all foreigners, didn't know what they were voting for, were old and thus should have their vote be ignored, and worse.

I might be missing some, I'm biased.
The left's attacks are more personal, more violent. I have an overly-simplified theory of why that is, the left's values are much more centered around the human, and the right's values are much more centered around the economy. That means that everything for the left is personal, it's cutting deep, violation of these values trigger empathy: sadness, anger, feelings of injustice and outrage. Violation of the right's values are much less personal, more indirect, closer to annoyance than outrage.
Of course, being biased I also think that the left's argument are more violent because they're _more true_, the right mostly getting its way. We do live in a liberal world which is very right-wing (despite americans liberal being called "leftists", that always confused me, or even "communists" when communism is so radically opposed to the neoliberalism we have today)
