I’m sure we can agree that a) such a Utopia does not exist, but b) we would like it to. The first step towards improving the world is recognising the faults around us and discussing them. If you are in a position to speak out, then keeping silence about serious social issues is tantamount to tacitly condoning them.
To me, at least, sovereign states are not holy entities to be treated with unquestioning reverence. I realise that for some (many?) Americans, on a conscious or subconscious level their country represents not merely a geographical and political body but also an idea (though not necessarily the same idea for all) that has resounded down the centuries. The abstract nation remains coloured with forceful ideology to an extent that is now quite rare in the Western world. But the fact that something has been around for a long time does not mean it is good. An idea can be a very dangerous thing- and national pride usually is. There is nothing particularly harmful about it if it is mild and for the right reasons, but more often than not I rather think that it exists either for the wrong reasons or, perhaps worse, for none at all.
And on a very trivial level, your pride must be a bit of a burden if a few remarks from me can upset you so much!
