I kinda get the impression the stance in a good chunk of Japan is to either play it as a joke or sweep it under the rug, hell with CERO they had to be coy with Persona, so it really may be that if they allowed homosexuality they'd be forced to have a different rating.Some ignorant people don't want kids to learn that homosexuals and/or homosexual relationships exist. It's mostly a thing in Amurica.
Nevermind god damn Russia.
