That all seems reasonable. Rape jokes probably aren't a good idea; it's possible they could increase the number of rapes in society.

Except there are all kinds jokes about "short man syndrome" and "small dick energy" going around that seem to completely accepted by mainstream culture and social media platforms. These phrases would not get you in trouble on Medium. I would certainly classify these as "derision" and "scorn" as you said, but because they're about men, it's apparently fine.

But try talking about "fat woman syndrome" or "Small tits energy" and just see what kind of reaction you get. If you were to say them on Medium, your article would be removed and you'd likely receive a ban.
