They have to be talking about the ambiguous Ruby/Sapphire=Garnet thing... it's the only gay in the series, really, but in fairness some of the stuff in SU does go pretty far and while I would never ever suggest censorship I personally feel a little nervous that I recommended it for my baby cousin to watch. I can't wait to get angry phone calls about why he's trying to summon his treasure troll shield and doing dangerous crap like jumping off of cliff sides and trying to merge with his girl friends...  I feel like it's comparable to PeeWee's Playhouse, in that there are things clearly designed with sex in mind... but it isn't like PeeWee's Playhouse drove a generation to deviance, either.
