1. Wearing a mask doesn't make you ANTIFA. 2. That you saw some property destroyed by someone who somehow was proven to be ANTIFA, is not proof that they are behind all destruction that happens.

In fact there has been reports of right-wingers also engaging in property destruction.

You can see plenty of examples of say BLM trying to get people to stop destroying stuff to avoid that they get the blame.

In short it is a pretty chaotic situation and a diverse group of people involved with different motivations and agendas. But of course you choose to exclusively blame ANTIFA because it serves your political agenda nicely.
