Eh I'd say a broad number of Thespians/theatre folk are gay. Both men and women. However I'd say generally it's like 50/50. Some are very campy and sunshine rainbow overdramatic. Others not so much. It's a mixed bag of everything honestly. That's what I've gathered from being in theatre so long. So there is some small truth but it's still a generalization that doesn't apply fully at the end of the day.

Why fo people think most male thespians are gay? Because they are very over-represented in this occupation.
I don't think most people will think you are gay for going to broadway shows. However, if you're hanging out the back of the theatre screaming like a little girl and waving your autograph book in their faces the thats pretty gay.
Uhm probably because a disproportionate are. more so than the avg. population. Think of it kind of like the WNBA vs. The NBA the WNBA is theater ( ironic lol) and it's been estimated that well over 50% of the league is gay (98% if you believe Candice Wiggins lol) While the NBA which represents the general population is a very small percentage.
