First, yes, Omar's statements have been troubling. But I've seen her willing to apologize and engage on them, without giving up her Central point that what Israel is doing is messed up, which most certainly isn't anti-Semitic.
Trump's actions span the range from being unable to condemn the events in Charlottesville to presiding over an administration that still houses children in utterly appalling conditions. Ie. it has going beyond troubling words and tweets to active harm. He has made ICE an instrument of Nazi-like sequestering and gross mistreatment of Innocents.
I cannot fathom the level of groupthink and blindness that would be required to equate stupid, thoughtless, even wrong, words to actual harm to thousands of kids. I disagree with you a lot. But this? This is truly disgusting.
