OK then Ironside, your knowledge of the exemptions granted to sikhs is extensive but I think you have been fooled by the christian lobbyists as they gloss over a VERY important distinction.
A sikh is allowed to wear a turban no matter what (more strictly, it is illegal to prevent a sikh from wearing a turban) and this does indeed mean that he does not have to wear a motorcycle helmet.
BUT, by taking advantage of this exemption he is not materially disadvantaging anyone else.
The christians are maintaining that it is their right - and only
their right, mind - to materially disadvantage whoever they want to, in this case they want to disadvantage gays by denying them an adoption service. The principle at stake is entirely different and much more far reaching.
There are lots of people in the world who believe it is their religious duty to blow up everyone who does not share their religion (i.e. american christians
). If ANY group is granted exemption from the law for the express purpose of allowing them to harm other groups, then you have just legalised islamist suicide bombing.
It's been said - you'll like this - that you should respect your neighbour's religion to exactly the same extent that you respect his theory that his wife is beautiful. I.e, so long as it doesn't harm anyone else then tactfully let him get on with it (but ONLY so long as it doesn't harm anyone else).
Me, if my neighbour has married a minger I'll tell him
