Unfortunately, the way that post reads:
"Nothing you've said gives either the current state of Israel, or the collective nation of Jewish people, the right to be commiting genocide."
Is not saying simply the state of Israel is committing genocide, but the "collective nation of Jewish people" is best case saying that the entire Jewish population of Israel is responsible. Worst case is they are saying all Jews, everywhere. Either way you cut it, it's an incredibly sweeping generalization, lacking in nuance, and is clearly anti-Semitic.
