Thank you, Mark.
That's the great thing about multiculturalism: it doesn't involve knowing anything about other cultures - like, say, the capital of Bhutan or the principal exports of Malaysia, the sort of stuff the old imperialist wallahs used to be well up on. Instead, it just involves feeling warm and fluffy, making bliss out of ignorance. And one notices a subtle evolution in multicultural pieties since the Islamists came along. It was most explicitly addressed by the eminent British lawyer Baroness Kennedy of the Shaws, QC, who thought that it was too easy to disparage "Islamic fundamentalists". "We as western liberals too often are fundamentalist ourselves. We don't look at our own fundamentalisms."
And what exactly would those western liberal fundamentalisms be? "One of the things that we are too ready to insist upon is that we are the tolerant people and that the intolerance is something that belongs to other countries like Islam. And I'm not sure that's true."
Hmm. Kennedy appears to be arguing that our tolerance of our own tolerance is making us intolerant of other people's intolerance, which is intolerable. Thus the lop-sided valse macabre of our times: the more the Islamists step on our toes, the more we waltz them gaily round the room.
Multiculturalism is dealt with this way in schools, too. Unfortunately.
