There's a difference between "norm" and "non-existent"
I mean, seriously, white people in European countries are the "norm". Non-disabled people everywhere are the "norm". Mind you, there aren't very bloody many of the latter in Disney movies either.
And I'm also tempted to echo the famous remark that just because something is -common-, it ain't necessarily -normal-.
While you're all busy wanking on about the bleeding obviousness of it all, and "art reflecting life", there is that 5-10% of us who are engaged in same-sex relationships. So where ARE they in the Disney movies? Or are queers automatically not rated G by our mere existence?
Also, I'm frigging sick of 99% of female characters being super-girlie, super-skinny and fans of pink. Thank god for Mulan.
