Salted slug has a well written piece on the UKs latest obsession with the “rights” of the religious.

So anyone whose religion (if they have one) doesn’t stipulate the obligatory carrying of a bladed weapon has to abide by the law saying that they can’t (Criminal Justice Act 1988, section 139), but anyone whose chosen superstition does allow said wielding can carry on carrying (Criminal Justice Act 1988, section 139A).
Not that I necessarily agree with the legislation in the first place (it’s not like knife crime is at an all-time low) but surely the fact that someone is a Sikh does not make them intrinsically less of a hazard to other people than the law plainly assumes the rest of us are?

“Chosen superstition” sums it up quite neatly I think but do go read the whole post.
