I will defend to the death anyone's right to practice any faith, if it breaks no law, interferes with nobody's rights nor claims undue public policy influence. Church bells, calls to prayer, displays of crucifixes, beards or side-locks are freedoms, alongside bare midriffs and knicker-short miniskirts. Personally, I am affronted by women in face veils, but that's my problem. I will argue against them but freedom of speech, thought and dress are non-negotiable. But so is the right to robust argument that may offend religious sensibilities, including the right to challenge the improbability of the faith itself – and the right to make jokes.
