1. Incrementalism--4+ decades of small, minor yet constant victories by the gay community in every facet of life have made QEFTSG possible. Marches, literature, music, education/indoctrination of children, infiltration, acceptance by liberals, and intimidation(PC). We've been beat down by a phallus-shaped brickbat for too long, and we're tired.
2. Whatever the media likes becomes a hit, naturally. Absolutely Fabulous was the "in thing" years ago. The media made a big deal of it, and the ratings grew, thanks to a small number of sheeple. And of course, a lot of the media is gay, and 99.9999% of it is gay friendly. I'll bet my left arm 60% of anyone and everyone involved with TV Guide is gay. It reflects in their writing, and current direction, into the gutter of our sex-obsessed culture.
That's still a far smaller percentage than that at Entertainment Weekly.
