Well?Do they have to officially sign up somewhere, or does the BLM sign they're holding count? Does BLM release their membership statistics? Playing ignorant doesn't help anything or anyone - just as some of those, on the other side of the argument, are playing ignorant in the chat on MRI in the football forum.
I've marched alongside BLM. They don't do that. That's a Fox News thing to keep mid-western white people afraid and watching.
In any protest there will be people that fall into your group, that are not part of your group, that have their own agendas.
Oh here we go again...let's blame a right-wing conspiracy on everything...straight out of Hillary's playbook. Just this week a BLM group attacked a Trump supporter, and that has happened many times.
Just out of curiosity, how old are you?
