Sargon of Akkad had a great answer to these idiots.
If the charges of white privileged and racism were true, when you called them such, they’d laugh in your face for stating the obvious, not trip all over themselves to apologize and try to prove they were not racists/privileged.
Good point, and that brings me to mind of what we—who happen to have been born white—ought to do:
Laugh at them. When they accuse you of micro-aggression, acknowledge it and tell them you do not intend to stop.
Tell them that being offended by the fact that you are white is not your problem but theirs.
Remind them that you do not EVER go down without a fight, if that’s what they’re getting to.
When they say you have white privilege, agree and laugh at your own fortune! Tell them that “White’s alright!”
In essence, if you can’t beat ‘em; join ‘em.
