"While I am entirely in favour of multiculturalism, I think that it is best left to occur of its own accord in a completely natural way....NOT to be manipulated by government policy."

Agreed!

"It's utterly absurd, this kind of politically-correct sounding attempt to gradually dismantle a country's own original identity and replace it with some homogenized version of "world" culture."

And that's why I find myself at odds both with socialism and with capitalism, because both seem to lead inevitably to just this sort of homogenization. I generally have no problem at all with religious people (of whatever persuasion) who mind their own business and treat others respectfully.
