In my experience, gays are proud and glad to be Americans. There aren't _that_ many countries where they could have what they have here. I have a feeling the 5% who are aren't proud are 18-year-old ANSWER and Amnesty Intl. members and their faculty tutors. (who I see assembling on the quad at my school every spring).
Obliviously, you haven't been the Gay Frisco Area.
