It's just your typical gender stereotypes; however there are double standards for women. Men that like MLP are called gay, neckbeards, etc etc, whereas if a woman likes a show aimed at boys she's seen as cool, edgy, funny, silly etc. No one cares if a woman likes Transformers, TMNT, Power Rangers, Batman and other shows that are generally aimed at the boy/teen male demographic. Women have always been allowed to like what males like, but it's not reversed due to men having to be the epitome of masculinity. But that is a much deeper topic that would require pages upon pages to explain.
