Racism is as old as humanity. It will never ‘go away’ entirely. Eventually, genetics will advance to the point where rational people know that it doesn’t matter.
Sex change operations were impossible 50 years ago. Will ‘race change’ operations be possible in another 50 years? Will some judge sentence a black man to being white for 90 days? Or visa versa?
Will it matter? No matter how much scientific progress is made, you will never be able to reason a man out of a position he didn’t take thru reason. Rational arguments will never alter irrational behavior.

BTW, The US Government officially classifies Arabs as white. So Ohhhh…..BAMA having a 75% Arab father makes him 87.5 % white. I’m not sure if that is enough to make his claim to ‘blackness’ fraud. I don’t think the feds use the one drop rule when it comes to determining minority status.
So it is possible any benefits, Ohhhhh….BAMA got for being black were fraudulent.
