It is important to send a message that this type of behavior is not tolerable. That being said, this was an event where the radical right was in the wrong. I expect an even handed response on both sides when the radical left does something similar. That includes Antifa, radical portions of BLM (I say radical because the original purpose of BLM was noble and there are still portions that are following that goal while the name has been co-opted by racist sects on the left lobbying for violence). While it will be a swift reaction from the right the only way for these movements to lose clout and be marginalized is that their mainstream politics equivalent denounce them. This time the right should denounce the KKK and Neo-nazis. Next time there is left wing violence I expect the left to follow suit.
