I think JayDubya probably isn't arguing in faith but I'll at least humor this. I've made it clear I don't like BLM the movement however there's nothing wrong or racist about "black lives matter" the slogan. There is no need for a "too" asterisk at the end. The argument is that black lives are devalued and not cared about, so the statement is a direct confrontation of that problem. Honestly I don't see it as too different from "black is beautiful" and other older statements that were clear responses to oppression.
I understand that some white people might not know that and thus are turned off; I'm not sure it's a great slogan for a political movement. That being said, if a white person still thinks the slogan is racist after having the explanation given to them...they aren't worth wasting more time on.
So the ball is in your court, Dubya.
