I'm well aware.

What you said was: "By contrast, one cannot become Greek just by becoming a citizen of Greece, any more than one could become Russian, or German or French. Unlike the United States (and a few other countries), most nations are ethnic homelands for distinct cultures. "

There's a big difference between "Many Greeks don't think you can become Greek just by becoming a citizen of Greece", and "One cannot become Greek just by becoming a citizen of Greece". The latter sounds very much as if you are indeed the one deciding. And you suggest that there's some kind of essential difference between the US and European countries about this, instead of merely a difference in how large a percentage of the population would express such opinions (which, as you note, varies from country to country in Europe).

I think you'll find very few people would "never" accept immigrants as one of them, though. It's a small minority of those voters who are genuinely, ideologically racist. The rest have just had a few too many unpleasant encounters with criminals or intimidating gangs of immigrant origin, and generalized from there, or are confused and frightened about half of the people in their neighbourhood looking alien and foreign. That won't stop them from building up quite good relationships with individual members of that immigrant community. Hell, most of the far-right parties have a small but stable number of votes from the immigrant communities themselves (probably my earliest memory of French politics is seeing a tall black man on television who was handing out leaflets for the FN, and getting yelled at from all sides - that certainly took guts).

Well, thank you for that clarification, because that's quite different from what your previous post said. With the above paragraph I only disagree on the numbers - not "vast majority" for the former, and certainly not "majority" for the latter either, in *any* country. Unless, I suppose, your definition of "accept" goes rather further than mine.
