Well, it comes off as silly on Doctor Who when they reference it in one-liners. There's already an openly gay actor playing Spock. Do they "need" to specifically reference gay characters on screen? It all depends on how it's handled I guess. Show a guy at a bar openly flirting with men/aliens/what-have you Captain Jack style like Kirk brazenly flirting with Uhura in the first film. It would be funny if handled right.
