It’s only racist in the skewed eyes of someone who sees everything based on race. You seem to think that Omar’s pigment makes her exempt from such criticism.
He also said You CAN go home if you don’t like it. He was making a point that needed to be made. He didn’t order her, he reminded her of the option if she thinks things are so bad here.
Btw, I agree with Trump - Omar is an America hating, anti Semitic person, and I hope she considers the option he pointed out to her. That’s not racist. He has mentioned the same for George Soros, and I also hope he takes that option though the people of Hungary don’t.
And finally, what was it in my OP that you found racist? I’d like to understand what you are thinking because I don’t see it.
