Here's my definition of what Nationalism is: It's having an appreciation, gratitude, and affiliation of a specific tribe, with a distinct culture, location, flavor, and identity that is theirs. The telling point is the last three words: that is theirs. It doesn't have to be perfect, it doesn't have to be better, it doesn't even have to be great. It just has to be theirs. It is not 'My Country, Right or Wrong," but just "This is my country. This is my tribe. This is my people. I was born here, I was raised here, I live here, I belong here, it is my right as someone who is alive to be here. There are many countries, tribes, cultures, and what not like it, but this culture, this tribe, this nation, and this home is mine. This is my Home!" It's having a place in the world, and being a part of a people. This isn't done out of hatred for the other but an appreciation and respect for themselves.
For too many people, they are not allowed to have a nation, a people, a tribe, or a culture. There is not allowed anything that they can claim as 'Theirs' Nothing they can be appreciated, grateful, and proud of. They are the ones who are atomized, gray, bland, and so small-souled that the Devil wouldn't buy them. These are the people who are cast out and rejected by the global village...and every other month you hear of one of them burning something down just to feel the warmth.
