Summary of the evening: it was my wife's birthday. My family got together. We all we're having fun.
While playing a board game, my brother pipes up out of nowhere: "Obama isn't actually black. He's biracial. Race is nothing but genetics." And a million other random Fox News esque talking points.
I tried arguing with him for a little bit, literally only trying to make the point: "Race isn't JUST genetics. It's also history and culture and other things." He begins flipping out.
We move on. Keep playing the board game. He brings it back up several more times. My older brother tries to talk rationally to him / figure out why he's talking about it in the first place. My idiot brother keeps escalating.
I eventually am so pissed that I got up, slammed my first on the table, and asked him to stop being a fucking child.
My very conservative family is shocked to hear me cuss and have an outburst of anger. My wife and I very awkwardly leave.
Thanks for ruining the night bro. I'm hindsight I should have just urged us all to ignore him. But fuck that was annoying as hell.
