"Tell me how my pointing out a moral double standard is "white supremacy"? "

Because you took a tragic event and made it about race, particularly pointing out a problem that you have with black people and making a generalized statement. Nobody else here tried to make this an example of what is wrong with black people, that was only you. Generalized statements about any race, are racist. There, done! See how easy that was? Hung you by your own words.

"You have very deep-seated issues with white people. You need therapy."

I am a white person. Being white doesn't require me to denigrate black people, but you act like I betray my race if I don't agree with your racist generalizations. That's your deficiency, hun, not mine, nor anyone else's.
