The coalition would crumble if it emphasized positive issues, such as “gay rights in Gaza.” So they focus on common hatreds. Those are what hold the coalition together.

Second, these hatreds have been stoked by the left’s “Long March through the Institutions,” which began with 1960s radicals who became professors and has now permeated K-12 education, both because of the teachers’ ideology and the unions’ political position. The Long March has been extraordinarily successful in achieving its ideological goals.

Israel is a prominent target of that ideology. Why? Because, for the left in the US, Canada and Europe, the Jewish state represents so much they hate, wrapped into a single package: capitalism, nationalism, Western religion and economic prosperity success thanks to hard work, intensive education and merit. ...

It’s the old cry of “Hey, hey, LBJ. How many kids did you kill today?” This time the epithets are directed by a new generation at the world’s oldest target: the Jews.
