Why are so few actors in Hollywood out of the closet?

Question

Why are there so few openly g*y actors?

Answer 1

Because they're afraid of being shunned. Either that, or they're straight

Answer 2

They're afraid it will cost them work.  The only openly g*y Hollywood actor that I can think of off the top of my head is Rupert Everett, and while he's well known, he's not in the superstar league.  It makes a very interesting contrast to Britain where g*y actors are accepted a lot more - look at John Barrowman who practically has National Treasure status in Britain - he's out and proud.
