Well, they did GI Jane, does that count?
You also have to remember all of the companies under the Disney umbrella:
Lifetime
Touchstone
Dimension
Hollywood Pictures
ABC
Miramax
So while they may not be the minds behind any "gay films", at the same time many of their movies and shows have gay themes.
I think it's great how they sneak in characters in shows like Ugly Betty (especially when Mark was dating the kinda bear-ish guy). It helps people get more acclimated to a gay presence than an in-your-face gay show or movie that many would just not watch.
