To be a part of a country or nation, you must both be of the culture and ethnicity - which is equally pertinent if not more so, however much this simple fact is to a liberal's dismay. There is a genetic component to how well you can assimilate cultural attitudes, as these have been selected for over that country's entire history (for instance Christianity in the West); if you're not American you can never be American. Furthermore, ethnicity is simply an extension of family, just as one naturally places their family over others (a natural biological impulse), one places their people over others; you can never trust or be trusted as much as amongst your own people. I don't even dislike you, simply I would rather you were separate and for your own sake as well. Multiculturalism and globalism dilutes cultures - the very thing which justifies living. Unfortunately, it is a shame you exist in the first place, but this often the case these days. Sacrifice the now for the future.
Oh and me? I'm 100% British.
