> That's all academic. Current nationalists base their 'nation' on skin color and religion: white and Christian (though the religious aspect is sometimes less emphasized), like ISIS'/Daesh's nationalism based on Islam. You can read people advocating it in HN, just like you can read many attempts to whitewash it.

That's somewhat true only in a very narrow world of USA and ISIS. In most of the world, nationalism is based on very different terms.

> One step this way, I love them; one step the other way, I oppose them? It's absurd.

Nah. Nationalism doesn't mean opposing anybody. It's belonging to community and working for it's greater good.

> Finally, nationalism is an obsession of a small group imposed on others.

Most people don't care about any political, societal or any other philosophical discourses. They just follow few people who are interested in that kind of stuff. As far as I looked all revolutions were imposed by a small group of concerned citizens on the rest of the community. I'm yet to find an exception where majority people truly believed in the original idea from day 1. They just followed people who seemed worthy.
