Gays have taken over the entire entertainment industry, you’d better go along with their agenda, or you can forget it.
Having worked in the industry, I can attest that you are essentially correct. Once it was only segments of the business (art directors, scenic designers, and makeup artists, for example), but now the agencies, studios and even production companies appear to be dominated by them - and they are not merely content to live quiet, private lives, but to proselytize, recruit, and harass heterosexuals whenever possible.
Having grown up in the 60s and 70s, I used to be quite accommodating of them, but their agenda has grown so aggressive and dangerous that I find I can do so no longer.
Gays had taken over by the 1970s. Remember Barry Diller, Allan Carr, Sandy Gallen, Joel Schumacher.....
