I know nothing about you except what I can infer from the little of you I have read. You know nothing about me, except for the little you've read, if anything at all. I will repeat; from my fortunate perch as a black person of great privilege, I have spent enough time between worlds that I know what racism is when I see it.
You seem to presume that black people are on the prowel, sniffing for racism the way predators seek prey. No, if anything, we need to be hyper aware in order to protect ourselves. As for me, because I live the way I do, I have the unhappy "privilege" of being surprised when racism smacks me in my unsuspecting face. FYI, for what it's worth.
