Hmm, well I guess for me it was part of a long process of losing religion, I was raised Catholic and it took a while for that to get out of my system. Once I had my eyes opened to the idea that all that dogma was a load of crap, I started to question everything, including traditional "morals", who set those ideas up and what they had to gain from it... which was basically to control people.
I think its one of those unfortunate things you have to deal with in aminority group where if you are in a large group of straight people then you can be thought of as "the gay one" whether you like it or not. Think of how often people get described by the colour of their skin, it's not intended as a racist thing but it reduces you to a physical trait.
From what you say about yoru media job, it sounds public and I can understand you wanting to be private about who you are. Having said that, there are more and more media people who are out these days, even newsreaders like the guy from CNN.
Gay events can be cliquey, no matter what type of work you do. But if you get yourself a good bunch of friends, then you can rise above it and not get caught up in the drama.
