From a twenty-something that has run the range of emotions on this topic, let me try to explain, because right now it seems like everyone is missing a big point.
Just because we are young, have access to more information, the internet, a more "accepting," culture, etc. doesn't mean that some of us didn't grow up in backwards societies, unaccepting families, or for some reason or another weren't comfortable enough with our surroundings to seek out help when we were dealing with the "coming-out process." (ps I HATE that term because it makes being gay sound like an adjustment to your life) There are lots of reasons for young people to be unsure of themselves when they are figuring out who they are, ranging from hearing their parents make crude remarks about homosexuality to being in High School and hearing "THATS GAY," 15 times a day. The society has changed, but the pressures are still the same, just like guys 30 years ago (and more), you still have to seek out the support, its not knocking on your door, and that can be daunting for a person who is already either scared of who they are, or not willing to admit it to people for fear of reprisal.
Thankfully, I just never gave a flying flit what anyone thought. Granted I didn't realize that I was gay until a random Saturday night when I was at a gay friends b-day party, got a little too into things and ended up in bed with a friend of a friend
. I was pretty OK with it, and set to letting people know that I was not really looking at girls anymore. It was a swift process, and thankfully I was at school, living in a major metropolitan area, and so had a supportive environment. However, when I went home and came out to family, it was NOT the same case, and there are some of them that still just flat out won't talk to me. It even took my mom a few weeks to speak to me in a tone that wasn't constantly threatening. I can imagine that had I not been so confident of myself, and willing to share that with other people in a constructive and collaborative manner I may feel very different about being gay. Unfortunately, not everyone has the same set of circumstances (or outlook on being gay) as I do, so I can sympathize when I see someone take a negative attitude towards being gay, but I still hope they turn around and understand that it can be a jumping off point rather than a weight on their shoulders.
