Omar spoke out against Israel, not Jewish people. We should be supporting freedom of speech, and using it as an opportunity for ending everything conservatives say being labelled "racist" or the words of Nazis. By not supporting free speech now, we just go further down the slippery slope. "Hate speech" is speech other people hate. It shouldn't be treated as a criminal act. It should be thought of as views which will openly be discussed.
I repeat myself. I support freedom of speech, whether or not I agree with what's being said.
