Why shouldn't I? You don't get to dictate how I "get" to feel. The very idea of racism and xenophobia is fundamentally offensive to me. As with the Amazon native population, I would not approve if they didn't let me in by virtue of some immutable attribute of mine such as my appearance.
So long as you make an effort to learn someone's culture, I don't think there's any justifictaion to exclude someone on the basis of the brute facts of their body or upbringing. Actions ought to matter far more.
I'm not aware of any moral theory that has been justified in academia or elsewhere which prescribes that such discrimination is permissible. This also is evidenced by the fact that many Japanese people claim to abhor racism while simultaneously practicing it against sections of their own population and other populations.
