Yes, it is indeed.

Because only a one country planet is acceptable right?

If the standard of measure and comparison is Nazism and the KKK, then that is a very very low standard to compare things to. Incidentally, Nazism in its purest state is not "racist" in the grand scheme of things. Karl Schmitt, the philosopher of Nazism, only argued about the necessity of the friend-enemy relation, the "us" against which a "them" is defined. Schmitt was arguing about the necessity of forcing the nation to be one, in response to previous philosophers such as Plato and Aristotle and the grander debates about democracy. He presented his theory as a form of refined democracy where the people are "made" to speak as one (hint: through the dictator figure of the Chancellor). In his theory, and influenced by Platos distaste of democracy, he argued that the origin of justice is an act of violence. Democracy cannot contain multiple voices because this is its undoing.

Hence the Volk, the people who speak as one... By not having to speak at all.

Coincidentally, his most famous doctoral student was Hannah Arrendt, a Jew who later suffered under Nazism and had to escape. She later wrote the famous book, The Origins of Totalitarianism, which is now considered one of the greatest works of contemporary German philosophy.

On a similar note, let us not forget the cultural openings of Hitler to muslims, which he thought could be friends and allies to the Reich. "The peoples of Islam will always be closer to us than, for example, France", he said, which is probably the closest thing to a racist and a nationalist calling someone of another identity as a "friend".

But I am digressing here. Ultimately, nationalism nurtures racism, like the sun's light nurtures the shadows cast by it. Nationalism distinguishes people between an us and a them. It is at its core. Racism is the natural outcome.

I'd prefer a no country planet. In any case, nationalism is bad because it results in people discriminating others because of their place of origin, something which people cannot control, so it's essentially the same as racism except for place of origin it's race.

There is nothing wrong with nationalism. Only mixed with xenophobia become ugly.

oh ok, so Nazi's and Hitler aren't racist, only vgchart posters you don't agree with are. Gotcha. Sounds pretty racist to me. 

In fact lets use your logic here:

"On a similar note, let us not forget the cultural openings of Hitler to muslims, which he thought could be friends and allies to the Reich. "The peoples of Islam will always be closer to us than, for example, France", he said, which is probably the closest thing to a racist and a nationalist calling someone of another identity as a "friend"."

A Hitler apologist.... Like every racist ever.

The core of nationalism itself revolves around an us vs. them mentality of people within a certain nation against those outside of that nation.

I have to disagree. European Union should be Union of Nations not a one country without a face. If we take Nations out of equation we will lose our identity.

I will say it again. The word you looking for is xenophobia. 

How would you lose your identity? Unless you base your entire identity on your nationality.
