Black Lives Matter is a Marxist movement. Someone who knows about living under Marxists understands what that means:

At first glance, it might seem that leftists and patriots have common ground in that neither side likes fascism. But they dislike it for opposite reasons.

Back when fascism was a significant force, patriots opposed fascism because it was a threat to freedom. Leftists opposed it because it competed with a still more totalitarian threat to freedom: communism. Leftists oppose fascism even now, pretending it is more than a historical artifact so as to associate it with anyone they want to destroy.
