Just a few thoughts...
If you were to offer a night for white men only, would that be considered racist? Probably by some it would be.
When it comes to sexual attraction, some men prefer men of color and some prefer white men. This is personal preference like a straight man preferring blonds to brunettes.
When we consider objectifying a man for his cock this can be seen as a negative. This tends to happen more with black men. A real whore probably objectifies all men and only wants them for what they can get.
If you truly want to do something, you do have power! The power to stand and peacefully protest, the power to add your name to the many petitions, the power to put down the racist views of others , the power to vote for representatives that are going to remove the racists from the police and other institutions.
Individually we may not change the world but together we can.
