Omar is from a corrupt shithole that happens to be a country in Africa. She hates America, hates Jews, and sympathizes with Islamic terrorists. But according to your twisted sjw logic, anyone from Africa can't be called out for anything. Gotcha.You don't have to explicitly use a racial slur or mention someone's race for your comment to be racist. Are you guys that dense?
If he was talking about black people and said, "You people are disgusting", it's the same thing. He still didn't actually say the word "black".
The reason why his tweet was racist has been stated a million times over already. He's basically using the old, "Go back to Africa" routine. Let me guess. You don't think that's racist either.
You want people treated differently based on the color of their skin or where they are from. THAT is the very definition of racist. It is divisive and destructive to society.
