It almost happened. Veteran Trek writer David Gerron (The Trouble with Tribbles)
wrote an episode for TNG titled "Blood and Fire", which was an AIDS allegory and involved two openly gay human crew members, but it was shelved by Paramount producers. Later it was made into a New Voyages episode, after it was reworked into an TOS episode. TNG had a chance to make history, but it blew it.
