If you don't care, then there's no point in mentioning the disregard of black trans killings. You've admittedly disregarded them yourself, so who are you to point out who should be regarding them, when you're of the same background and don't even care.
Again, just because you don't identify with the LGBT community, doesn't mean others shouldn't or don't. They do, and are actually doing something within these black neighborhoods. And that's all I will say on that matter.
