I am not sure that the issue of the demographics of the actors is that important vis a vis to their ability to play the roles. In the original casting: Leonard Frey the actor was gay and Jewish and he is just perfect for the role, no question about it. On the other hand, Cliff Gorman was straight, and his version of Emory is terrific and very convincing, especially to people who don't know many gay people; his best work is during the truth game and drops his cloak of camp invincibility. Lawrence Luckinbill is straight and he fits the role of Hank very well, nice guy. The character of Alan is probably straight (or confused or something) I think, and actor Peter White was apparently straight. I am not sure anyone knows whether Reuben Green, who played Bernard, is/was gay or not. I love them all. Actors should generally be selected for their ability to create the character I think.
