I for one am very proud of being Swedish. You may have noticed
(yay, the smileys are back to normal!) However, I'm not proud of it for any particular reason. I don't consider the virtues of my country to be greater than any other country's though. As such, I'm one of those who is proud of his place of birth, as some of you just said. So... what's wrong with that?
As long as I don't consider myself better than you are because of it, I can't see what anyone shouldn't be.
I like it when things turn out good for my country, and I wish the best for it. As such, I'm considered a nationalist. Though I'm far from one of those bad nationalists you keep hearing about.
I do absolutely see the many flaws of my country, and I sometimes get pretty pissed because of the idiocy our government rule the country with. I love my country, but not my government, so I have to disagree with whoever said otherwise (my computer is half frozen, so I can't scroll down and check who said it).
While I'm being proud of my country, that doesn't mean I need something to rely on because I myself hasn't achieved anything. On the contrary, I'm very proud of myself as a person. I know I'm a great guy and that I've made people's lives better. It's nothing I brag with, I'm not that kind of guy who goes around thinking I'm better than anyone else, far from it.
I love my country, but it's no more than a country. As such, I can make fun of it and let other people make fun of it as well (it doesn't harm anyone, so...). Then again, I believe that we should be able to make fun of just about everything (almost), so you might wanna ask someone else when it comes to that.
So my point is that it's deffinately okay to be proud of ones country for no other reason than being born there, and there's nothing wrong with wishing the best for it, as long as you dont consider yourself better because of it and as long as you don't start putting your naton in front of more important things.
