You know, while the gay rumours are pretty silly, arguing that he *isn't* gay is just as silly, really. I mean where in canon does Tails' sexual orientation even get mentioned? Sure, in Sonic X he likes a girl, that doesn't preclude him from liking both, so really... until Sega officially says "Tails is Hetero/Homo/Bi/Asexual" it simply hasn't been dealt with. And in a series mostly aimed at kids? Serious relationship issues don't seem quite the appropriate thing anyway. As for "Sega wouldn't be silly enough to include GAYNESS!!!!!11" arguments, society is slowly viewing homosexuality more and more as just as normal as heterosexuality, so homosexual pairings that are as non-explicit as heterosexual pairings in media for children probably will end up being more common eventually.
