If a person's occupation is, "Professional Protestor", I immediately question their authenticity where it concerns achieving justice and equality. Some of these leaders in this BLM movement seem more like vultures than paragons of justice and equality. They will tweet but I have yet to see any significant work being done outside of protesting and tweeting. Protesting and tweeting are good, but only good when backed by actual work.
EDIT: I agree with the concept of Black Lives Matter, and I think it is a good movement to be honest. I just think it was poorly executed because now we have outside interests in the movement with their own agendas. Muddling our issues with intersectionality only stifles the message of Black people trying to achieve justice in an unjust country.
