"The difference is that the thread originator is concerned that English culture will die out (not that other cultures are not as valid as English culture), and the belief is that stopping some kinds of immigration will prevent this from happening. I don't happen to agree with this idea myself, but it's not racist."

The politics of seige have been used in many places to justify bigotry. The "our culture is under threat" chestnut is a favourite of the BNP.

"I love our world being multi-cultural", but not wanting to see any of that multiculturalism in England, is one of the most fundamental tenets of xenophobia: "I don't mind them, as long as they're not over here."

I'm afraid I disagree with you, Carol. I think these views are not only racist, but they are of a particularly nasty variety, as they try and couch themselves under a veneer of acceptability.
