Should kids & family movies have gay characters?

It's a weird, friendly kind of discrimination that categorises life and says "put this type of person in in order to please people and keep everything equal," completely uninspired and fascist, but then what would I know, maybe a gay character works for the film and was an inspired choice not from any political correctness system.

I hate that kind of control, it's not about unity at all, it just divides, and yet they claim it's about unity, but it's still based on shallow identity and appearance, making space for someone because of their race or gender or sex is still discrimination in exactly the same way as excluding someone for race, gender or sex, it's still confining people and life to shallow identity/race/features/sex etc.  I hate anything like that, that says "this type of thing is good," or "this type of thing is bad" as it's going by type and imposing a system of discrimination that blocks inspiration and feeling, disruptive black-and-white.  I've seen this kind of thing pollute many films, disturbingly a lot of family films/kids films, like indoctrination.  

Kids & family were the only movies where it was possible to relax from the every day madness.

I disagree, any great film helps you relax from every day madness and washes it away, no matter what it is about, if you're willing to take a step back yourself.  It's just the best films, of any genre or era, were never skin-deep.  Even films filled with brutal violence/horror can be uplifting for the ideas and themes and the way they're expressed, never violence for the sake of violence like in sadistic control-freak films.
