"I'm not saying you shouldn't criticize Netanyahu or Israel but maybe be a but more critical of who seems to be leading that criticism."
This is actually a completely valid argument. I've followed anti-Zionist blogs before and stopped because they started pinning the problem on "the Jews" instead of Israel, Zionists and their genocidal project. The Neo-Nazis in my local area used to do a weekly protest where they'd hang out downtown with "Death to Israel" and "The Jews are controlling America" signs.
Like, yeah, Death to Israel. Death to all Israeli colonizers. But also, be critical of some of the voices of those who claim to be on your side.
