I tried to think of a detailed response to this...and all I can come up with is that nothing you've ascribed to Rep. Omar follows from what she said. She said that Israel abuses human rights, which is true (and it's true of every country in the region, but again, Omar's disgust towards the Saudi government goes unnoticed), she said that she shouldn't be called unamerican for not pledging loyalty to Israel, which is also true.
How you get to you being disloyal to America for a qualified support of Israel is beyond me.
