The cure for edginess is growing up. The cure for fascism is a bullet in the head.
Ethno-nationalism is definitely thing. But if that's the same thing as fascism, then the entire western front of WWII was a huge inter-fascist struggle.
So what do you think fascism is, and where do you think it exists? Could you point me to a website of fascists?
EDIT: Thinking about this further, if fascism = ethno-nationalism to you, or even ethno-nationalism + a dictatorship, then Mainland China is arguably a fascist state. How many hundreds of millions of them do you think should be shot? That's a lot of bullets.
Apparently I’m a nazi, because I believe in liberty. Are you advocating this for me?
