The point I am trying to make is that while people can argue endlessly about how there are theoretical differences between anti-Zionism and antisemitism, the rage that Jew-haters and Israel haters exhibit are absolutely identical. Antisemites and anti-Zionists are equally irrational, equally obsessed and equally wrong.
If racism and antisemitism are wrong because they are examples of irrational hate, then that same hate is immoral in any context. While the Israel haters would argue that they have justifications for their obsession, so do antisemites, racists and xenophobes.
There's no difference.
The only thing that can explain the seething and manic, obsessive hate for Israel is the fact that it is the Jewish state. No one has the same hatred towards Syria or China to the point that they say that they have no right to exist. Only Israel is such a target.
