I see where you're going, but I don't think Disney has to make anything "gay themed". That's a purely artistic choice and personally I find movies about gayness extremely trite and tedious. However it is homophobic to pretend that gay people don't exist. If a company had a policy to keep Jews and black people out of its films, I hope you'd agree that would be racist. It's equally anti-gay for DIsney to pretend that a significant slab of the population has no role to play in their stories. Whether or not Disney has a social responsibility to children is an interesting question. I'm not sure I can answer it, but it is the case that we learn an awful lot about the world from the media we consume, especially when we're young. I don't think anyone can dispute that Disney has a huge impact on kids.
