I think that we as a society could draw a line separating depictions of consenting, same sex adults, and embracing surgical transitions of minors.
I know a lot of people, Disney often included, don't, but we could and should. Two adult women kissing is not any more intrinsically immoral then an adult man and women kissing. I checked the Disney Wiki, and Woody and Bo Peep kissed in the first movie, back in the benighted 90's. So there's at least precedent in the franchise. I'm not sure where possessed, enslaved toys fornicating falls on the spectrum from Apple Dumpling Gang to forced 6th grade transitions.
YMM, of course, V, but I will posit this: If the "Culture War" is as hot and earnest as many seem to believe, I don't think maintaining that adult, consensual homosexuality is immoral is a winnable position anymore. That view through the Overton Window has slipped by. I think the sexualization of children's media in general, hetero- and homo- is more of an issue, but I don't think adult kissing is overly sexual for kids. Hell Empire Strikes Back had an incestous kiss, and it was a kids movie.
