Are all religions equally valid?

Prescriptive pluralism is the idea that a multiplicity of faiths and cultures is not just an observable fact in the modern world, but something which is right.

All religions ought to be promoted as equally valid. This is the approach adopted by politically correct multiculturalism.

On the surface it sounds good. But the corollary is taken to be that therefore any group which claims to have ‘the truth’ in such a way that other faiths are deemed untrue or wrong is not to be tolerated.
