Maybe the media wants to push black and gay TV presence in reaction to the craziness of the times. Logical? Perhaps not. But if that's the case then it's hard to argue that they aren't hiring the best people for that goal.
This is just my $0.02. If I don't like something I don't support it. If enough people in enough demographics are turned off by over saturation of particular groups, and then turn off their TV set in turn, companies will take note and start promoting more balanced content.
In the end, I simply don't care enough about skin color to be bothered by it. White family, hispanic family, middle eastern family...just sell me your home security system, or insurance, or new 2021 Subaru BRZ.
