Kalita, the 'gay plot' as you call it, on 'Six Feet Under', is (and I hope no one will yell at me for this... but it's kinda true), much larger on SFU than on BtVS. SFU is based around the lives of the Fisher family, who own and run a funeral home. The two sons, Nate and David, take on most of the responsibility of the home and are arguably the show's two leading protagonists. David is gay, but struggling to accept it, he is out to his family, and they are very accepting of him.... however the conflict resides in the fact that David's family are more accepting of David's homosexuality than he actually is himself. His plot is much more central to the core of what SFU is as a show as compared to W/T on BtVS, so it is probably more 'deserving' of the kind of awards that GLAAD likes to give out
If they had a cutest couple category, than i think we all know who would win that
