If I am repeatedly asked the same questions, and if I do always tend to be frank/open in my answers, then, Sedayne, those answers are going to be similar.

someone who does question immigration may OR MAY NOT be racist

I agree. However, someone who questions immigration on racial grounds is racist; the same goes for anyone who advocates a mono-racial society. "we are dealing with culture here NOT race" - so what questions are you going to ask at the airport, to decide who gets let in? Can they sing "Greensleeves"? That's most of the English population out...
