No, I think you're talking about pluralism, or possibly liberalism. Democracy is definitely about majorities, at least in the dictionary that lives in my head. My statistical samples are entirely unscientific and subjective, and I'l freely admit that. Nonetheless, with asylum and immigration now rated in proper scientific polls as the third most important issue for voters, I'd be willing to bet a hefty sum that a majority of those voters aren't saying that because they want a more liberal regime.
