Of course they did. From this point on, if she said that grass is green they'd label it anti-Semitic. The fact that Miller is a white nationalist--and a piece of shit, but she didn't say that--is utterly irrelevant to them.
Rep. Omar's use of anti-Semitic tropes is well recorded elsewhere. Claiming they are merely anti-Israel is a distinction without a difference. When Muslims complain about the support for Saudi Arabia as loudly as against support for Israel, that might suggest a gleam of rationality and fairness. I won't hold my breath.
Let's be clear though, of the three main western religions, Islam is horrifically violent and antithetical to western civilization and science (Though the other two aren't really far behind. Fortunately, Jews have practically abandoned the more primitive dicta of their Holy writings).
He is a Jewish Nazi/White Supremist, the lowest of the low in my book. His family is ashamed of him. He is the biggest POS.
To be sure, Omar and Miller are both bigots of the worst sort. The problem is with Miller who is directing national policy. That Miller is Jewish is bizarre. Is he another self-hating Jew? Where did he get his racist values? No need to guess where Omar got hers.
She is not anti-Semitic but anti-Zionist as this cultural Jew and many others are here. He is the biggest POS ever!
Omar is not bigot! She is speaking the truth!
