OP gives off “biracial” vibes or he's a Black man who grew up and hung around one too many cacs so his perception is skewed, dude has probably never dated a Black woman a day in his, especially not one of a browner and darker complexion considering he posted a biracial woman.
Or he could be just a full-blown cac;
I mean, y'all said he's a staunch MAGA supporter/Trumper who posts suspect shyt from time to time

With that said, nobody cares or seeks to know what your preferences are...boasting about it when nobody asked is just looking for attention, but also, it's like you're seeking approval to validate your choices because, at the same time, you're unsure about yourself so you need others to agree and join in so you don't feel alone.
