I don't feel that position is anti-Semitic either, but I think it needs to be noted for the sake of intellectual honesty. He is critiquing a LOT of Jews here.
I'm all for charitability, but it feels like we're contorting ourselves--why would any tolerant person with a decent penchant for writing not keep a wider berth between their criticism of Israel and antisemitism? I understand that there are always going to be bad faith people who willfully misinterpret all criticism of Israel with antisemitism, but those people aside I've never found it particularly difficult to criticize Israel in a way which is unambiguously tolerant of and respectful toward Jews (and he seems like a better writer than I am).

"If I were a Jew I would be concerned about my insatiable appetite for war and killing in defense of myself," (…)
"If I were a Jew today, my sensibilities would be tormented. I would find it increasingly difficult to reconcile the long cycles of oppression that Jewish people have endured and the insatiable appetite for vengeful violence that Israel, my homeland, has now acquired."
It just became “If I were a Jew I would be concerned about my insatiable appetite for war and killing” in the tweets.
