Nationalists aren't super my nation best regardless, if anything they're super pissed off when their leaders do stupid shit because it makes the whole nation look bad.
If you have blatant proof to the contrary that X is worse than Y in some regard, they'll not declare I win regardless. With America those who're American Nationalists don't think America is the best because Muh Merica they believe America is the best option in the world providing the best opportunities in the world and while it isn't perfect, it is the best option. Does this mean let's say France has a better health care system, (I dunno for sure since never looked into the French systems) and the US lacks behind them, they're going to say America needs to improve on that front instead of "No America best!"
If you asked a lot of people who voted for Rudeman or for the Brexit party in the UK, do you approve of immigration where they are legal and pay their fair share, they'll agree with it for the most part.
Sure you'll get the ship them all back to where they came from rhetoric, but that's the same on either side of the spectrum as many are happy for as much undocumented immigration as possible even though this is both illegal and destroys a nation's internal structure system.
There are certain things that make America, America and Britain, Britain. To replace them lessens that and ends up making the nation not that nation.
Say you removed all the Brits from Britain, is it really Britain?
If I replaced tomorrow all the people of Indonesia with people from the Congo, is it really Indonesia any more? Geographically, sure it could be, but the culture and people of Indonesia is gone.
Nationalists want their nation to do the best they possibly can. But this doesn't mean drag down other nations.
If you have a child, you want them to do the best they possibly can. You don't start take out the other children to prove yours best.
And even if your child isn't the best at anything, you're still proud that they give it their all and represent themselves to their fullest.
However you can argue X nation is superior due to their morals, laws or traditions and arguably is superior.
Although arguably nationalism is vital to a nation's survival. If a nation doesn't identify itself on a collective people of beliefs and values, it doesn't really stand the test of time. Sure people disagree on issues, they still are of that nation.
The Winter War in 1939 or 1940 I forget, the Soviets misjudged the Finnish Communists as being more sympathetic to the Soviet forces over their own Finns and so when they expected Finnish forces to join them, they found them against them during the Winter War. Nationalism ties into Ethnic shit due to the nation's history, if someone was asked to describe a British person or a German or a Russian person, they're not likely to say a 6ft dark skinned person or 5ft yellow skinned person. The nationalistic view of the Finns made those on either side of the extreme unite to fight a foe who threatened their homeland and lives.
The same with describe a typical person from Africa, you're not going to say some Charlie Chaplain looking fellow or someone who looks like Teddy Roosevelt.
Each of the nations of the world has developed differently some vary greatly while some have small differences. Each race needs their race respected, be they French, German, British, African, Chinese, Japanese, Native American, Indian and so on.
Nationalism however for some reason is associated with Nazi Germany, Fascist Italy, the Blackshirts of Britain and Imperialist Japan and some others that I can't remember off the top of my head. It is more or less complete demonetisation of the word. All of those used Fascism of some form, Imperial Japan I may be wrong on since I don't really know much about Japan other than it recently came out of Feudalism during the 1900s and had only became a world power so to speak when they beat the Russian army and navy in the war they had in the 1910s. Also look up the Russian Baltic Fleet, fuck up after fuck up just making their way to fight the Japanese.
The word isn't that bad, it just means a love for your nation, for example as a Brit, I disliked Theresa May, I felt she was a bad choice for the nation and I feel she poorly reflected the British people, however, as much as I dislike her, I cannot decide the nation is bad because of it, the nation is still above her and any other Brit and all we can hope is the next leader chosen is able to properly represent the nation as for my faith in Boris, it is yet to be seen, he at least makes me laugh so there is that. And in clown world, least we have an actual clown in command.
I'm gonna go pass out now or have a wank, don't @ me.
Also note to self drink more rum.
