Why is giving your sparkledog mental disorders hip?

Protip: It's not. It's grossly offensive to those who have had to deal with it. Schizophrenia isn't just hearing voices lol, bipolar isn't just going from happy to sad, and autism isn't an excuse to act like a fuckwit. These are serious disorders and you treating them like an accessory is a douchey thing to do.

You wouldn't give your fursona/sparkledog AIDS or cancer, why treat mental disorders the same way?

This isn't just for sparkledogs, this is for everyone out there who thinks claiming to be mentally ill makes you cool.

EDIT: If you've done the research and it's true to the disorder (i.e. one of my characters is a paranoid schizophrenic and he believes that "they" are responsible for everything from misplacing his car keys to molesting him while he sleeps. It doesn't make people go "LOLOLOL HOW RANDOM" it makes people cross the street to avoid him) then that's peachy.

But if you're adding it to try to make yourself unique and completely trivializing the seriousness of the disease, then go hang out with someone who has that disease (who isn't a 15 year old DA brat who got the diagnoses off an online quiz) for a day and see what a moron you are.

If you're going to add a mental disorder to your character, do it. I can't stop you. But at least make it true to the disorder. Depression isn't just feeling sad occasionally. Schizophrenia isn't just hearing voices. Bipolar isn't just being happy sometimes and sad sometimes.
