Anyone who calls you a bigot, racist, or whatever, purely because you initially think of/react to others in a certain way can go f*** themselves. Some things that we find alien/different/odd will inevitably be percieved as scary, there's a reason for that.
Xenophobia is just one aspect of our survival instinct, it's just like whatever psychological mechanism we have that keeps us from trying to pick up snakes or to pet tigers, for instance.
You can't trust everyone and all that. And the more different from you they are, the harder they are to read, and the more careful you'll be. It's instinct, and sometimes very useful. Our psyches just work this way, partly it's a remnant of how we were in harsher times, but it's still useful, as all of us can't be trusted.
They say that when infants (and possibly adults as well) smell something (truly) unfamiliar, it'll automatically smell bad, this is just an aspect of the same thing.
