If you're saying that it is fine that merely mentioning a fictional character is gay would offend a significant portion of MOTU fans--I strongly disagree. It's not. it's ignorant and hurtful.
And I am still confused as to how this discussion keeps veering towards children and what is acceptable for them. Is anyone really arguing that a kid reading in a MOTUC bio that two characters are gay would somehow harm them? Really? Just reading that gay couples exist is damaging?
