Incorrect, they had an entire series where a new homosexual couple were part of the monster of the week style episode.
I recall one military one, where one was called, one and the other, the other one. Which oddly suggested in the far far future homo in military wasnt accepted. Odd if you are pushing a gay agenda.
I recall a gay couple at a pub.
Other gay entities, mainly pushed very hard at you.
Which again makes them seem unreal, as if gay on tv must be odd rather than 'normal' makes me dislike the introduction of such characters, why not have a normal character who happens to be gay, which for the most part the lizard and her wife were, and hopefully will remain to be.
