How would you know who the fascist is unless their free speech is protected?
The same way my ilk once dealt with organized scabs, torture out of the first few and them shootup thei meating place.
Why would you want to know who the fascists are? If you do then that means you gave them power. In the US fascists not only have free speech protections, they have greater free speech rights than anyone on the left. They were given- through federal legislation- the power to control all media outlets. Fascists will never allow leftists to have a platform. Centrists will never allow it either. There is no practical reason at all for the left to defend free speech for Nazis, yet they continue to do so.
Notice “free speech” is in scare quotes. The previous comment isn’t suggesting that free speech should not be protected. But rather they referring to the fact that many fascists claim that to criticize them, or to refuse to promote their views is to stifle their free speech.
