I am saying that, in the circumstances where a white police officer killed an unarmed black person, Antifa's ideology is to be on the side of the victim, not on the side of the police. When there are protests about that death, Antifa's ideology is to be on the side of the protesters, not on the side of the police. And Antifa isn't afraid to mix it up in the streets. If they're going to be fighting in that situation, they're going to be fighting the police, not the protesters.

That does not imply that all who fight the police are Antifa. Logic doesn't work that way.

What I am saying is that, if outsiders showed up, and if those outsiders were not running a false flag operation, then their behavior fits that of Antifa better than that of the alt-right.
