Bay, I have to give it to you-you have one hell of an imagination!
Considerig the gay male poulation accounts for just 3-5% of the overall male population, I highly doubt your position that the vasy majority of men on Getbig are gay-closet or open.
But if it makes you feel better buddy-I'm down with it 
This is way off topic, but what you’re saying does not make any sense. Let us assume your 3-5% figure is correct. Even if it were, it does not preclude people of similar dispositions from concentrating their limited numbers in specific venues, for example a gay bar or a bodybuilding outlet.
We have a saying where I come from: don’t listen to what people say, listen to what they do. Ted Haggard and Larry Craig both insisted they were ‘not gay’ yet they were slurping cock when their wives were not looking. Most guys here make similar claims regarding their heterosexuality, yet they specifically choose to spend their leisure time patronizing a sport populated by gay men and male prostitutes—attending shows, buying videos, magazines, etc. No, not every bb fan is gay/bi, but the number is far larger than you seem to think. I don't have 872 private messages from people who just wanted to say 'hi'.
There are many things I do not know, but I DO know that if I were straight, spending my time and money to look at/admire scantily clad men rubbed down in oil who pose and flex to music for audiences of cheering men would not be high on my list of priorities.
I could be way off base, of course; maybe I’ve been biased by all the ‘straight’ guys in and around this sport who have wanted to milk my cock, but I am certain there are more gay, bi, and bicurious men involved in bodybuilding (competitors/fans/officials) than straight ones. Again, forget the labels. Just look at people's behavior. Look also at the early icons of bodybuilding—Sandow, Joe Gold (I better stop there…)—all were gay. As ever, like attracts like.
