If Zach and I have said it once, we've said it a hundred times: Beneath every anti-Zionist there's an anti-Semite (corollary: not every "critic of Israel's policies" is an anti-Zionist). Here's an excellent example.
There's a poster on the HP called Bill Sampson that I'm sure we've mentioned before. He routinely spews anti-Israel talking points, and what he doesn't have in originality he makes up for in aggressiveness. Here's a couple examples.
Nothing too new here. Describing Israel as an "illegal and criminal entity," describing the Zionist immigrants to Palestine as "criminals" and "thieves," making the classic strawman argument that Israel's existence is justified because of the Bible. Extremely aggressive language opposing Israel's existence, but remaining true to the anti-Zionist rhetoric. Nothing explicitly anti-Semitic (beyond the "Khazar" myth).
But not long after these comments are posted, another one arises. One that makes things a little clearer.
Key sentence: "In 1948 the Jews owned less than 6% of the land which they manipulated the simple farmers into forced selling their land using the typical usury, loan sharking and terror tactics."
This post comes so close to sticking to "mere" anti-Zionism but that word "typical" slips in and explains everything. Jews use the "typical tactics" of loan sharking and usury to get their way. Once you believe, as Bill Sampson does, that Jews (not Zionists!) are greedy thieves, then the creation of Israel is seen that way. It's just one in a long line of Jewish crimes. But it's not the "injustice" of Israel's creation that lead Bill to his anti-Zionism, it's his anti-Semitism and prejudices about Jews that made him an anti-Zionist. And this comment proves it.
Bill is just another in a long line of anti-Zionists who have slipped out and revealed their anti-Semitism. They just can't help themselves.
