In my view a huge part of the problem is that we keep giving bad people a benefit of the doubt they don't deserve, and keep treating bad faith nonsense as arguments worthy of consideration. In my view I am not making a "personal attack" so much as calling a spade a spade.

To be clear: I believe OP is not just ignorant, but is being a bad person. OP's point was not simply that anti-black discrimination is no big deal - which would be reprehensible enough - but that the opposite is happening, to the detriment of whites. It doesn't matter if OP is parroting racist propaganda or creating it themselves: it is highly potent racist propaganda, designed to convert whites into overt racists by playing on their resentment.

OP isn't "less racist" if they sincerely believe the propaganda due to misinformation: racism is racism and OP is perpetuating it. "Just because he's repeating a racist lie does NOT mean he is a racist" is unfortunately a common line of thought in the US. But this only assuages the feelings of whites, and does not accurately describe racism in America.
