You're full of shit. If it is pointlessly juvenile for one side to substitute idiotic violence for political discourse then is is also pointlessly juvenile for flabby cheerleaders like you to cheer for the same in the other direction. Lots of people deserve a smack in the mouth, but be careful about wishing that everyone who deserves one gets one. Nothing productive along this line of non-reasoning.
If no one fights back against the violent left's street thugs, then the street thugs win.
Talking is not going to stop Antifa.
And those willing to stand up for what they believe in against marxist thugs, deserve to be celebrated.
That is what an healthy society does. Celebrate those that fight for it.
