I have before but not cuz I set out to. the particular 1s I dated were cool. not much to report seeing as I didnt select them for their non-blackness.
I will say that dating 'out' is a hassle cuz no matter how progressive or well intentioned, in most cases they r still gonna be tone-deaf to to certain things. Any of the qualities I like in an individual non-black man, can be found in a black man. except with a black man, I'm less likely to have to explain shit. That could be avoided if you date non-black people of color but even they can be on some bullshit sometimes.
On a more superficial note, it doesnt take many generations for blackness to filter out of a bloodline. I'd prefer black descendants.
