They’ve already been promoting polygamy. I worry that is the next cause.
On the other hand, they may be dropping gay shows because maybe the gay thing has played itself out in terms of ratings and no one watches it anymore. These things do run their course.
In the end shows do have to make money. I think.
I think they’ve run their course because characters were getting too cozy and physical (kissing, etc.), and heterosexuals are normally repulsed by that. As long as they were a “cute” funny couple with little physical interaction, heterosexual viewers could cope with that.
