That's about right. Trump needed a scapegoat for his peeps to attack. He couldn't use protesters because they had growing support of the public. BLM would have been perfect because of their close ties to the democratic party but that could hurt his chances of winning Black voters. Antifa was the next best thing; besides it would be payback for Charleston.
OR...it could be that Antifa was clearly a primary factor in the riots not only in Minneapolis but New York, Oakland, Seattle, Chicago....whereever there are disaffected radicalized punks with a bent for violence
and an unshakable belief they have the right to attack "bad people" because they are virtuous "anti fascists"
and by definition to oppose them is to be for racism and fascism.
Therefor, the people who get hurt have "got it coming" and you are either for them or against them.
If you lived anywhere near Portland, the way I do, you would realize how they operate (Andy Ngo) and how the little rats get coverage from left wing politicians (Ted Wheeler).
Who were all the young white people in the riots smashing things and setting cars on fire? Are you familiar with Occam's Razor?
