It doesn't have to fit every single issue for every single person.
Agree. I love Disney, loved the parks in America and the people who were at parks represented every section of society.
I hate TV shows and films which are trying so hard to be uber-inclusive and diverse and it's almost like a tick box exercise - the black character, the asian character, the gay man, the lesbian, the person with a disability, the single mother, the step family, the transgender person, the wheelchair user, etc etc etc. Characters are written not for their acting skills or contribution to the movie or TV programme, but because they are diverse. That makes for a rubbish movie.
Some series do it well - the lady in Silent Witness who does all the techie stuff who just happens to be in a wheelchair and the girl who plays a similar role in Vera.
But starting planning a project with the "right, let's write a story where Elsa gets a girlfriend" is just a recipe for disaster. The story and plot has to come first and as part of that if they can make a character black/gay/disabled that's great.
