The BLM movement, like many causes, started out fairly noble. But it has been hijacked and overtaken by the types who just want to run around yelling things like "F*** White People", which is just bigotry, and has absolutely nothing at all to do with saving black people from being killed by police. If anything, their attitude, activities and rhetoric are compounding, not improving the situation.
I have no love for bad cops, nor of the general "untouchable" nature of American police to begin with. But too many of these BLM protestors, like ANTIFA, like "Rad Fem", etc., act like a bunch of entitled kids who just want to be angry and "F*** Shit Up".
