I've just been on the Black Lives Matter website to find out more about the movement and found this:
"We are self-reflexive and do the work required to dismantle cisgender privilege and uplift Black trans folk, especially Black trans women who continue to be disproportionately impacted by trans-antagonistic violence.
We build a space that affirms Black women and is free from sexism, misogyny, and environments in which men are centered."

"Cisgender privilege" and ooh look we are centring the men whilst stating we aren't 
I'd be interested to see statistics on black transwomen in relation to the above claims and compare them with various other statistics.
I'm too tired to get all my thoughts out but that privilege comment has really got to me.
