Jeremy Kuper has written a fluffy sort of article for the Guardian about his reflections on the circumcision of his son. He states none of the really significant aspects of the tradition, but nor is his piece offensive. It's fluffy.
The interesting part is in the reader's responses. Almost without exception they're highly negative; many of them are crude secularism of the lowest form.
Given that circumcision is done by Jews,Muslims, many Christians and others, this is not necessarily antisemitism. Some of the comments definitely have the whiff, but what seems more significant to me is the general frame of mind. Beliefs often come in clusters, and it's well known that the Guardian and its readers can't stand Israel, and here's another strand, quite separate - or perhaps not so separate.
