Gravitation is made for all viewers' pleasures. It is NOT just for homosexual people. It is just like any other anime. And the anime doesn't just focus on homosexuality. It focuses on friendships/relationships, music, and to add to that, it has quite A LOT of comedy in it, too. That's like saying, "You watch Sailor Moon, hey, that means you want to have super powers, and wiggle your pink wand around!"
