As stated by Black Lives Matter.
From the Black Lives Matter website page where they describe their beliefs and values, quoted around June 10th, 2020.

So justice, according to BLM, has to do not with race, but with
SEX
and getting rid of a belief in normal historical and traditional one man one woman relationships.
One does wonder how a black church deals with this BLM belief that goes against their understanding of family.
Speaking of family … BLM wants to eliminate family:
We disrupt the Western-prescribed nuclear family structure requirement by supporting each other as extended families and “villages” that collectively care for one another, especially our children.
So what’s the deal with sex, anyway?
We make space for transgender brothers and sisters to participate and lead.
We are self-reflexive and do the work required to dismantle cisgender privilege
In other words, men who are masculine are unacceptable and women who are feminine are unacceptable.
Does that sound intolerant and divisive? And how does it advance normative black people’s equality? It doesn’t.
