It's not so much disgusting as it is self-destructive. You exclude your political allies. Then you take the people closest to your cause and take aim at them rather than the people opposing you. Nice work. That's the attitude that got Trump elected in the first place, so it's kind of fitting I suppose.
Any black woman is just going to lose that pissing contest when they come up against some black, gender-confused, gay, paraplegic woman who says other black women just don't acknowledge their privilege. And then the black, gender-confused, gay, quadriplegic woman who then disses her for not checking her own privilege.
