The article you linked looks like someone had a personal vendetta against that artist. It does not seem connected to the rise of violent leftists.
Yes, isn’t that a handy distinction.
You are the one mockingly referring to brutal attacks on artists.
When the day comes that you or any of us find ourselves under attack by club, knife or gun, because of what color we are and/or what values we hold, do you think it will matter a damn what banner the attacker believes he represents?
Go enjoy your little art fair, with all the “ex”-Dems like yourself, and pretend only your world exists. You’ll find out otherwise soon enough.
