You pulled that out your ass fam. If we add up all the black characters on all the noteworthy or semi-noteworthy shows on television, there isn't 20% gay representation.
Furthermore in terms of the 3-5%...that sounds like a white dude argument when complaining about black people on television. Should black people make up 13% of the total characters on TV? Is population total the deciding factor? Those "forced diversity" arguments are the creation of racist whites. Let's not borrow their bullshyt.
My issue, as I said earlier in relation to Charles Blow's argument, is that the roles are often wack. It's a mixture of fetish shyt and boardroom marketing wankery. Oftentimes, gay stories aren't even being displayed in these shows...that's how you know it's suspect. I'm not going to say every black character should act like Kima in The Wire, whose sexuality was almost entirely in the background instead of the foreground. Or that every gay black man should be masculine on TV. If I'm going to see a gay story I want to see a spectrum of experiences - just like I want to see a spectrum of black stories. Not just the black cop, or the black gangsta. Likewise for gay shyt...not just the "buff black guy who acts straight until he kisses a white dude."
