As a Jew with many issues with Israel and no loyalty to them or love for their policy against Palestine, I have no problem critiquing both them and Omar's past remarks, which I believe often straddled the line of ancient antisemitic dogwhistles pre-dating her lifetime. I don't believe Omar is an antisemite, but I believe she's occasionally used antisemitic language that dates back to at least the turn of the century. I'm not okay with that.
That being said, I feel she is a gifted activist with a strong voice who has the potential to become a very effective politician - or to flame out completely. Either way, I feel the attacks against her by the right wing are vile and dangerous and that she should be protected. I can feel many things at once. And yes, I have had dumb kids who think they're lefter than me try to tell me I "cosigned" Omar's death threats by taking exception to her past behavior, well before those attacks began. I'd never do that and I find the current attacks on her repulsive.
