Personally I have to confess a very strong dislike towards Zionism. That much can certainly be said of me. In this context, and especially during specific moments of Israel history, I'm pretty sure I have made similar or worst remarks. And yet, I'm far from being an anti-Semite, since I'm a strong supporter of religious freedom, I admire many aspects of the Jewish religion, have Jewish friends, defend the right for Jewish cult and despise anti-Semitism. And all this, despite the fact I'm an atheist.
So, there's a context.
Similarly, if in a feat of anger after having being fooled by a Australian cashier, I say something in the lines of "f*ing aussies!", while I find that deplorable and will certainly regret having lost to anger, that will not mean I'm anti-australian, or hate the Australian people. Or, that would put a dent on my marriage.
