Remember that couple who was in the news a few years ago, after their child was born, and how they aren't telling anyone said child's gender? They named him/her Sky, and said they're letting their child choose his/her gender.
But it doesn't work that way. You don't just pick a gender like you do a pair of shoes. Ever heard of
David Reimer? He was the victim of a botched circumcision as an infant, and a psychologist convinced his parents to raise him as a girl. For years he felt like something was wrong with him, until finally his parents told him the truth when he was thirteen.
My brain just exploded.
If you stop and think about it, isn't this comic kind of insulting to actual trans people? Most people I've talked to who are trans say it isn't just putting on clothes of the opposite sex and poof! You're okay. It's a lot more complex. I certainly would NOT want to swap places with them, not in a million years. People don't want to have sex changes just for shits and giggles, or just to be "in", SJWs.
