You don’t make everyone leave who looks a particular way. Whether they’re Hasidic Jews, Muslims, Blacks, Chinese, whatever. That is exactly what racial bias is: treating people as a category based on appearance. There’s a lot of racial bias in the world. This incident happens to be about Anti-Semitism. Many other racial groups suffer this crap every day. There’s no excuse for it, no matter who it happens to or who does it.
