@Marja The problem with you equating fascism with "left-wing extremism." (this is called "horseshoe theory" & was most famously used in Trump's "both sides" speech in 2017 btw):
Fascists: we want to use violence to seize power and then forcibly remove or eradicate those we see as inferior outgroups, esp. racial outgroups.
Extreme leftists: we want to stop fascists from hurting people.
You: See? Both sides should be treated equally!
