When people compare something an individual supports/enjoys as a "mental disorder." Example:
"Being a lefty/righty is a mental disorder."
"Being a fan of Sonic/My Little Pony/Steven Universe, etc is a mental disorder."
"Loving video games is a mental disorder."
Um, no. I make alot of messed up jokes, but I'd never go out of my way to compare something to people who have mental health issues like depression, anxiety, multiple personality disorder, etc to try and act like a point you're proving is "the right one." I used to be friends with a guy who's very hardcore republican that once said "believing there's more than 2 genders is a mental disorder" and I already lost alot of respect for the guy after hearing that.
