erm... why is this even an issue??
<shouty, shouty, shouty>
I would consider being straight fairly normal, I'd also consider being gay fairly normal... what people seem to be using "normal" for here is to mean average, most of the population is straight - it isn't 50/50.... that's neither a good nor a bad thing, it's just a fact.
Ofcourse, everybody who's ever truley known somebody gay knows it isn't a choice, it's not your upbringing either - it's just who you are - one day you realise you are checking out your friends dad instead of their mum and suddenly you think "oh - I'm gay!!". Personally, I'm straight... my younger brother is gay though, and one of my best friends is gay - but none of us have ever had the conversation that maybe the Little Mermaid should have been banging the witch not the prince, or whether Sebastian was a gay sidekick (thinking back, he totally was!).
But these are kids films, and being a kids film, usually it's the parents who will choose the film, and therefore I'm assuming a male/female love interest will sit with their model of suitable content for 7 yr old Sally (if they've had a kid biologically together, and arn't "living a lie") than a lesbian mermaid trying to lick and octo-witch's stamp - basically because it's following their family model... or they've never really thought of it, but also couldn't care less.
Personally, providing it's not covert-porn I'm not going to worry Disney's portrayal of relationships to my boy just yet - but at some point I will sit down with him and have the conversation about relationships, the types that are out there, and that's it's fine either way, and that he shouldn't judge others or worry about being judged (at least by his family) - but that will be when we see he's ready for that, and not when some pressure group decide they want their box ticked in a Disney film.
