Indoctrination comes from the terms instruct and doctrine
So does any character in the movie state (instruct) - hey it's great and normal to be gay? (doctrine) if not, then there is no indoctrination
Does the teacher state; look kids its great and normal to be gay? (instruct) & (doctrine) - therefore indoctrination of kids.
Does the teacher state; look kids - how revolting and sick it is to be gay? (instruct) & doctrine) - therefore indoctrination of kids
So if a teacher merely shows a movie that beholds no instruction - and refrains from personal opinions - then there is no indoctrination.
Later the kids can and should discuss the content of the movie with their parents. Then it would be up to the parents as to how they might want to indoctrinate their kid/s
There is absolutely nothing wrong in raising the awareness in kids towards LGBTq's - it's actually important - so that kids can be protected from LGBTq's or becoming one.
It's like showing a movie were a character places his finger into a socket, therefore raising awareness towards a danger, and not indoctrinating kids to place their finger into a socket.
I watched a movie together with my 7 year old daughter - when a scene suddenly appeared showing two man kissing each other. Kids at that age in general find kissing awkward upon watching/witnessing it onto others. So my daughter gave me that usual eek look - upon seeing that scene. It was then me who shrugged his shoulders - giving an eek impression back to her and saying; two boys kissing - yuk. And she laughed and we continued watching the movie.
So now being 7 years old she witnessed a scene with two men kissing each other - I am dead sure that she will be seeing a lot more of this in the coming years-even in live. This year we might also meet up again with a cousin of hers, who is a lesbian (the male one). If she asks me about it - I will tell her that, .... is a nice and smart person, but due to her parental situation as a kid, she developed a mental distortion - resulting into her to become a Lesbian.
So now what is the fucking problem with watching that Disney movie for a 11-12 year old? aside from the usual American puritanism? That e.g. finds it abhorrent to display a pair of good looking naked boobs on the cover of a media magazine? - which would actually inspire ah... indoctrinate boys that there is something natural and yummy yummy to discover?
