They do if they are real liberals, if not, then there is no liberalism at play...
It's not just in the streets. Liberals at universities routinely ban and censor conservative speech. Then there was the Georgia teacher who kicked some kids out of her class for wearing a MAGA shirt. Intolerant liberals like her are pervasive in education. Facebook, Twitter and other social media routinely black conservative speech while allowing ISIS and Jung-un to operate unabated. Message boards operated by liberals frequently ban conservatives and/or have different rules for people depending on their political ideology. The American left does NOT support free speech.
You keep abusing the word "liberals", do you not know how to describe people but in only two paradigms?
When I was in college they banned many things about speech, but it wasn't liberals doing it...I myself as a liberal have never tried to ban anything about people expressing themselves..I believe wholeheartedly in free speech..That is liberalism...What you have here is some militant political movement of autonomous self-styled anti-fascists that oppose fascism by direct action... ..Hence they are not liberals-duh..They are misguided political lunatics that like you, don't know what fascism really is...
There are differing definitions of fascism. What many of your fellow Hillary voters believe is that, if one is nationalistic, you know, putting the interests of their citizens first, they're fascist. Lots of people around the world have been nationalist. There is nothing wrong with being nationalist.
Violently suppressing the expression of others was and remains a tactic of fascists, which many of your fellow Hillary voters apparently are.
As I said earlier, it's not just in the streets where "the left" acts to silence conservative speech. It's endemic.
Many on the left support free speech and many others do not and the ones that don't seem to dominate the ones that do. The ones that claim to support free speech are largely mute.
