There has been a lot of talk over the past two weeks about whether it is anti-Semitic to oppose Israel’s attack on Gaza. Radical Leftists and liberal commentators have insisted (perhaps a bit too much?) that there is nothing remotely anti-Semitic about their anger with Israel or their fury on behalf of battered, bruised and bombed Palestinians. And of course they are right that it is entirely possible to oppose Israel’s militarism without harbouring so much as a smidgen of dislike for the Jewish people. Some will oppose the war in Gaza simply because they are against wars in general, especially ones that impact on civilians.
