They are not leftist and they are not afraid free speech. People like Charlie Kirk and Alex Jones can say whatever they want to, but forget that there are consequences to saying disturbing, hateful things or lies. These people are protesting what Charlie Kirk has said.
Only the government is prohibited from infringing on free speech. Citizens and corporations can and will shutdown lies and hate speech. To put it in personal terms, nothing in the first amendment requires me to let you run your mouth.
Oh yeah, quote Fox Not News and Tucker "my face looks like I need to poop all the time' Carlson. LOL That will really prove your point. White Christian Nationalism at it's finest.
