To echo what others have said, though, if you are not a member of a minority, it can be difficult to understand how affirming and wonderful it can feel to experience, just for a brief moment and even if by fantasy, to exist as if you were the majority. For example, I am gay, and here are some common thought processes that go through my head that are basically completely foreign to straight people:
1. When I walk down the street with my partner of 20 years, deciding to hold hands is not something I can just do spontaneously. It is essentially a political act when I do it, and so my first thoughts always go to (a) am I safe and (b) do I feel like making a political statement right now.
2. When I travel, the first thing I think about is whether I am going to a place that is accepting of gays. I'm just too old to want to deal with anti-gay attitudes when I'm supposed to be enjoying myself on vacation.
3. When I introduce myself to new people, I do a mental calculation as to whether I feel like mentioning my partner and thus outing myself in that situation. Again, it's always a conscious calculation, where it almost never is for straight people.
So the first time I visited the Castro (a well-known gay neighborhood in San Francisco), it was kind of magical to me, to just walk down the street and have people assume I was gay before assuming I was straight, and it was really the first time I could completely relax and feel like what it was like to be a member of the majority.
So that's what things like BET, LogoTV, Telemundo, etc. are really about, it's about actually feeling like you are the focus of attention for a short time.
In the sense that shows and movies seem like the result of endless series of meetings, where anything that anyone might object to is censored and removed.
