I *can* love good health and junk food. However, one is not reconcilable with the other. The same is true of Multiculturalism and loving your country. A stable, functioning society that will endure will not endure long as a multi-culture. That's not my opinion, but a historical fact. But that all depends on what you mean by multiculturalism.
Also, you mention British Culture as being "Blander That Decaf Tea". Personally, I really don't care if a culture is exciting. If it is, that's fine. I'm not against it. What I really want to know if it works for all its citizens.
With due respect. Is that why you like Multicutraulism? Because it's exciting and not bland? If so. A culture being exciting is not the same as it being healthy, pragmatic or working for all its citizens.
