You have all the rhetoric down pat, good for you. If someone doesn't take to virtue signaling the way you think they should, they are "whining" or "not trying". I guess you feel comfortable seeing everything in "black or white" terms. You're a good performative ally. Personally I've joined organizations, donated money to Black prisoner organizations and Indigenous Americans (Blacks are not the only oppressed people in America, in case you haven't noticed), participated in a few protests, wrote to a couple of congress people. What have you done? Instead of attacking people that you don't know anything about, perhaps you should look in the mirror.
