In an ideal world LGBT Pride would not need to exist because all sexual orientations would be treated as absolutelly normal, so one's sexual orientation, no matter which one, would be as deserving of pride as, for example, one's eye color, i.e. not at all unless one is some kind of narcissist. LGBT Pride is really just a response to a World that in most places sees minority sexual orientations as "wrong".

I suppose you could divide that pride into two parts, one deserving of as much pride as one's land of birth and another really deserving of pride:

• The first, pride in one's sexual orientation (be it LGBT or any other including the majority one), is as deserving of pride as the nation one was born into, which is not at all because one does not choose how or where one is born and hence, not being an actual personal choice, it's not something deserving of pride.
• On the other hand the other part, that of an LGBT person having pride for having fought for and manage to living life as they are in an environment which discriminates against non-majority sexual orientations, is indeed real, deserved pride (IMHO), as it's pride in one's achievements.

Anyways, my point being LGBT Pride as openly celebrated isn't pride in the common sense of the word, but quite a lot more than that.
