Remember that stamp I made about "Fandom Has No Gender," and I told you that it is really sexist that people can accept girls being Transformer fangirls, but when it comes to guys being bronies (MLP fanboys) they found it creepy or a sign of homosexuality?
The same thing goes with making OCs:
If a girl makes an attractive female OC, they (mostly female haters) instantly labled that OC as a "MS," but if the girl creates a handsome male OC, the female haters are okay with that and accept the male OC.
Same goes with guys hating a male character a male deviant creates, but love the female OCs the guy artist created.
Get this through your heads everyone, there's no such thing as "Mary-Sues" or "Gary-Stus"! Only good characters, bad characters, bland characters, minor characters, fan-made characters, and over-used character traits.
I mean whatever happened to the original concept of characters being someone we can look up to, and wish to be like them?
Most characters like the comic-book heroes, fairy-tale princesses, and many more are suppose be like that because they are not real, but we can learn from (most) of them.
As for the crazy hair and eye colors, what's wrong with being a little creative on that? And fancy-words just make the character sound interesting, it would be boring if the traits were just like any other people you see everyday.
And who says that a character can't be imaginatve but still have realistic flaws and personality?
It's okay to hate a character if they a trait that irks you (like being mean, rude, slutty, etc.), but you can't go off hating a hating a character in just a blink of an eye without getting to know them first.
As for making some characters like/love ones' OC, you can't stop that. Everyone going to do that trait once in a while (no matter how over-rated it is).
The canon characters don't belong to any of you haters, so you can't go off telling what characters should be paired with and not be paired with. It's just the artists' imagination and opinions just for the sack of fun and creativity.
