A member of my band is gay, and he spent several years during the first years I knew him hiding that fact from the world. Only when I began to really get closer to him did I find out his "secret". He asked me if I cared, and the look in his eyes was that of fear. Fear that I would immediately reject him because of his internal chemistry. But I didn't, and we remain friends and band-mates to this day. He later grew up a bit and came to find out that being gay isn't so bad, in fact there are a lot of things about being gay that are rewarding and awesome. He's much more comfortable in who he is today, and much happier as a result of it. His choice to act upon and embrace his homosexuality, rather than shy away from it, made him an all-around better person.
That's pride.
