I'm quite pleased at how over the years (I've been lurking on these forums since the days of the AMD Duron

) OcUK has become quite accepting and suchlike. I remember those old days where threads like this would have been plagued with posts about how "un-natural" gays are and things of that ilk. Glad to see it's changed for the much better.
Proud of you guys!
Thankfully, as society matures (in a variety of different ways) people who hold onto this kind of out-dated & simplistic mind-set go the way of the dinosaur.
It's cultural evolution, with sadly a few Cro-Magnons still hulking around watering down the social gene-pool.
I can totally understand the need to 'come out' later in life, I can imagine school being incredibly difficult for people who are of a different sexuality to the majority & that experience making coming out as an adult much harder.
A couple of my school friends who came out waited until college/university - specifically for that very reason. Public figures coming out changes in part helps change the social attitude, I'm sure Stephen Fry (by being adored & followed by so many heterosexuals) has done a great service in combating homophobia by simply a example that gay people are just as capable as being intelligent, funny & witty as anybody else.
It's akin to how the early African American comedians in the US did a great service to equal rights, as it changed the public perception of them - it allowed people to connect on a level with people normally who would be distant, it's this very connection which works best at combating racial or sexual prejudice.
Clearly it would be better if they didn't have to come out & the contributions socially made by people who have been openly gay the entire time would be larger - but it's completely understandable & most certainly is a force for positive social change.
Essentially, any group which suffers from unjustified negative prejudice in the wider population benefits from positive public figures who represent them for reason above, along with providing an example to the given group that they have nothing to be ashamed of.
