. I can't remember what I said at the time. My current thoughts are that sexuality is complicated so I don't think
sexuality should be a barrier to which actors get which parts - after all, I imagine many (most?) gay actors would be pretty hacked off if they were told they could no longer play straight characters.
However I do think people casting roles should be wary of "immitating personality traits". Not all gay people are camp, so I don't think it's an issue for a straight actor to be playing a character whose personality matches their own but just happens to have a different sexual preference, but I *do* think it's an issue for straight actors to... umm... "camp face"(?) and immitate stereotypically "gay character traits" that are not actually part of their own personality. Just find an actor that better matches the character.
