Of course I don't deny personally valuing my family and friends more than strangers, but that doesn't mean I think they fundamentally are more deserving of jobs than strangers. I would personally help a friend get a job before I would help a stranger, but I still think that Americans are no more deserving of jobs than non-Americans, and I don't believe that is a contradiction.

Edit: I also don't think we should be under a one-world government, and I don't see how that follows.

I am fairly convinced that economic protectionism is bad for economic growth, particularly in the long run. And even if I'm a direct beneficiary of a certain protectionist policy, I'd like to think I will oppose it, because it's essentially equivalent to the government taking resources from a non-protected job sector and giving them to the protected job sector.

Nice try, but nationalism is not an intrinsic trait of being a human.

This sort of tactical nihilism is honestly pretty confusing to me. Borders, whether national, ideological, social, tribal, linguistic, etc. always have some level of arbitrariness to them, and yet they still represent useful categories. The house door that you lock every evening is merely a collection of arbitrary atoms arranged to separate what you imagine to be your property from others. In the framework of nations, the idea of treating citizens differently from non-citizens as being "discrimination" is an odd one. A country belongs to its people; it doesn't belong to those across the arbitrary border. We all make (sometimes arbitrary) restrictions on access to that which we value; humans who don't do that usually end up losing them to those who do.

That has always been my aversion to nationalism, because to me it occupies the second group in trying not only create loyalty, but much like the company, try to usurp natural loyalty. The power of which I've seen a family member go into nationalism's deep end and strain our relationship with them because I didn't agree.
