I support criticism of Israel. I think a lot of it is unfair, but a lot of it isn't. In general, I support it. Even for Israel's sake, I think that if they are wrong, it could be catastrophic for them, easily as bad as just letting their defenses down, completely.
I just see a whole lot of this as being something entirely different from criticism. It looks hateful to me, and I feel like that hate is being given a pass, ignored or even embraced as an ally, for sharing in criticism.
How many rail against Zionism, but don't really even know what it means? Or worse, maybe they do? How many people agree with them, just because they're mad at Israel?
When your criticism goes beyond a state's actions, to criticising its very existence, hating anyone who even believes in it, that isn't just criticism.
When you compare Israelis to Nazis, or their Prime Minister to Hitler? Either you really believe it ..or you really don't, but just like saying it, anyhow. Either way, that isn't just criticism.
