The Wikipedia article on patriotism has a nice statistic, although it's a bit old[1]. A few countries were asked how proud they were of their country, from a scale of 1 to 4. Most of them are in the 3 range (with the US leading with 3.92), Germany had a 1.37.
Again, this isn't really about what you want to express, it's how you do it. And a phrase like "Deutschland über Alles" is basically somewhat between "The South will rise again" and "White Power".
Personally, I find team jersey mentality like that a bit narcissistic, but if it floats your boat... But if you're about to improve the image of something, you shouldn't use the terminology of those you're opposing. That just makes it look like a battle between two equally wrong splinter groups of the same cause.
I think it is safe to say that what was written in the article was done so deliberately to get a rise from people who want to be a bit "ra-ra".
Nationalism is simply having pride in your family. To "stamp out" pride in your nation means that you have to "stamp out" pride in your family. The family is the basis of Western Civilization[2], and if you destroy the family, you get a lot of very bad and unwanted things as a consequence (like mass welfare and a halt to scientific progress).

but saying that its frowned upon to be proud of your own country (regardless of country), is to me, not a nice thing to say. singling germany out forever because of past events is dis-ingenious.
i would say that anyone whose nose gets bent out of shape because a german says they are proud of their country probably needs to take a second look at germany, and then themselves. and if a reporter is doing this, then it is most likely just stirring the pot
