No, WAV, it's the questioning of having multiple cultures in a single country, on the grounds that a homogeneous culture is a really important value - more important than individual freedom of movement, for one thing.

When I say someone has racist views, I don't mean that they aggressively dislike people of other cultures or that they wish other countries would abandon their cultural traditions. I mean that they believe that a person's cultural background is a really important fact about that person, and that people from different cultural backgrounds should be kept apart. In short, believing that countries ought to be monocultural (as you clearly do, although you're too mealy-mouthed to say so outright) is racist. So this "how dare you call me a racist?" act isn't ever going to persuade me - or, I think, most other people here.
