Just what is the Zionist "left" for?

It's become quite fashionable in Zionist circles to say that criticism of the State of Israel is permissible. This is usually tacked on to the notion that the last of the colonial settler states is a democracy and that criticism is allowed in a democracy. And here's an immediate problem. How meaningful can any criticism of Israel be when it comes from people who say that a country that denies the majority community the right to even live there, let alone vote there, is a democracy? There have been many analyses of Zionist "leftist" positions. This is the latest that I have seen and it doesn't simply criticise the Zionist left, it seeks to expose the motive behind its dubious brand of politics.

In general, the most important function of the Zionist "pro-Palestinians" is to enforce two boundaries in the discourse:
1) the legitimacy of Israel as a Jewish state;
2) the illegitimacy of violence against Israelis.

The first of these boundaries seeks to legitimise or ignore the ethnic cleansing of Palestine by the Zionist movement in order to establish Israel as a state for Jews with a Jewish majority. The second seeks to legitimise the massive use of force against Palestinians. So that's what the Zionist left is for.

This needs to be exposed. Much has been written about anti-semitism rearing its head on the left and even in Jewish leftist circles but very little is said about the more than passing flirtation of some leftist groups with Zionism.
