Gays are what? 7% of the population at the very most? Yet gays are vastly overrepresented in the media compared to their actual numbers. It should be easy to see this stuff would have a limited audience, not enough to make a lot of money. But the "mission" dictates their work, not the business. Black people are also greatly overrepresented in Western media (Asians are underrepresented), but that's slightly different and comes with its own unique issues.
