Even if
A racist genocidal state must die...
is true, it doesn't make this true:
“Death to Israel” isn’t antisemitic.
You're wishing death upon Israel. What group of people predominantly live in Israel? Jews. Semites. Thus, antisemitic.
And if your solution is for Israel's government to just disappear, you'll be surprised to find that Hamas will treat the
Jews, Christians, Muslims, atheists and pagans
no better. Don't act like Hamas is offering the pinnacle of freedom from religious persecution. Let's not forget that this is the same Hamas that has endorsed jihad against Jews.
