Are Leftists in Favor of Open Borders?

Juan Cole isn't:

The first original sin was the contradictory and feckless pledge by the British to sponsor Jewish immigration into their Mandate in Palestine, which they wickedly and fantastically promised would never inconvenience the Palestinians in any way. It was the same kind of original sin as the French policy of sponsoring a million colons in French Algeria, or the French attempt to create a Christian-dominated Lebanon where the Christians would be privileged by French policy.

One of the more plausible reasons to be dubious of Zionism is the fact that open borders are restricted to Jews. If the first complaint about Israel is that it is based on immigration, then the quarrel is no longer open society vs. closed society but tribe vs. tribe and I may as well stick with my own and, for that matter, born-again American Christians may as well stick with Israelites.
