Sorry, kiddo, your "I'm liberal" racial shaming pass isn't redeemable here.
I have not the slightest clue of what you mean by this statement.
Never in my life have I ever heard anyone being accused of being white for "critical" thinking. I have no idea what type of friends you hang around but they are very unique for all the wrong reasons.
Also I still don't know the definition of "black culture". Jamacians, Hatians, Nigerians, Ethopians, Somalians, etc. all have different cultures, yet they're all "black", so how can you say there's a "black culture"?
