I think everyone needs a reminder that fascists don't need "an excuse" to do fascist violence. Fascists do fascist violence when given opportunity, not when given pretext.

This is not some "start" to political violence. The fascists are already doing fascist violence, and have been for quite some time.

They will likely claim it as their reason for new violence, yes, but you shouldn't take fascists at their word. That would be a gravely dangerous misunderstanding of fascist behaviour.
