As someone who leans left, I don't agree with Omar's opinions on nearly anything. AOC is not dumb. She's extreme in her green new deal but she's not dumb, no matter how many meme's you guys make of her. Most of which are make believe.
I took about two looks at the site and had never seen it before. Yes, I was basing it solely on race and the graph showing America losing the white majority by 2050. Considering everyone in the image is non-white, anyone could have taken that position. THAT, may not be what is driving you but it is most certainly driving many on the right.
