I completely agree.
Positive role models are important for children, and there aren't enough gay ones.
It has been shown that many children are aware they are gay long before they are aware of sexuality or romantic issues - they just know. Having a character who they can relate to as part of the television they watch is essential for developing self-esteem and confidence.
There is no reason to bring 'sex' into it either - if a female character can have a crush on a boy, a female character can have a crush on a girl - we already have characters having crushes in children's shows, so nothing more needs to be added other than changing who the target of the crush is.
Since you brought up MLP - Rarity has a crush on Prince Blueblood. There's no reason Rainbow Dash couldn't have a crush on Spitfire (a female pony) and be just as appropriate.
Ah, okay.
Let's look at the implications of the statement in bold letters here.
There aren't enough positive role models for homosexual children -->
That means that those children can't relate to straight characters, and can't regard them as role models,
what in return means that a heterosexual person can't relate to homosexual characters,
and is unable to regard a homosexual character / person as role model.
Nice trench-digging I have to say, inconspicuous but effective.
But rather counterproductive for all participants, when I'm not mistaking, so I discourage people from doing so.
OT: I wouldn't mind homosexual characters in children's cartoons, as long as that doesn't bring a sexualized atmosphere with it. While this may seem unlikely at the first glance, I point at the fact the fact that adding new / unfamiliar aspects always holds a certain danger of degeneration, nothing against homosexual characters just a case of "better safe than sorry".
Consider, heterosexuality is the norm, thus the implications and the resulting general atmosphere can almost be described as asexual.
That's not really something we should risk too easily.
In case of Rainbow Dash: I wouldn't mind if she turned out to be homosexual, but remember that the introduction of this aspect should be executed appropriately.
A little thing I wanted to add: While the idea of those characters is okay for me, I regard the absolute, unreflecting demand for them as evidence of impertinence.
TL;DR:
Homosexual characters in children's cartoons are generally a decent idea, but the realization should be careful, appropriate and correctly evaluated.
