You're right. Allow everything that a culture somewhere finds OK. Knives under cots? Sure, why not. Dogmatic teaching from a young age? It works abroad, why not here? Never offend others sensibilities, so everyone must take shoes off before entering a house of Mosque. Mustn't let police work offend anyone. Polygamy? Well, rather legalise it than cause any offence. Cutting sheep's throats in the back garden? Well, if their grandfathers did it we can't change them can we? Church bells causing offence? Better stop them too whilst we're at it. The Queen is defender of the Faith. Clearly that's discrimination. Better scrap that too.
