Disney's market is certainly mostly made up of parents who are not going to the movies with children under 10 and hoping to get a change to explain sexuality. Me, personally, I just wanted to talk about how funny the talking sloth was, not who he was dating. If you think 5% is significant, than it is. Oh, wait, just re-read this. You don't have kids? -XC
I don't have kids. My point about the sexuality, though, was that parents already have to have that conversation with kids about straight couples. Broadening the talk to say that anyone can fall in love with anyone else doesn't make the conversation more difficult. And, as you rightly pointed out, Disney movies should not be gay-themed. They shouldn't have sexual themes at all, but that doesn't mean you can't have gay characters just being there. They already have straight characters falling in love, but they're not movies about heterosexuality.
Dude, parents don't have that conversation before they have to. And, yes, actually, adding edge conditions to any conversation with a child makes it much longer to explain and much more likely that they'll do/say something hideously embarrassing in public. -XC PS - Three kids, I have some experience at this sort of stuff.
You've got experience on me for sure. But does seeing a gay couple on screen really pre-empt that discussion? You're already seeing straight couples on screen. By showing a gay couple kissing you're not showing any level of adulthood that wasn't already there. Also, I suspect kids are going to embarrass their parents no matter how hard you try to stop it!
