I hope one day people like you realize that no matter how you spin, it's body shaming and damaging to mens' mental health. Small dick energy literally states that you're giving off the energy of a person with a Small penis (and in every context, implies that's a bad thing). No amount of justification or adding energy to the statement changes that.

Imagine you're a girl who has small boobs and the popular insult going around is flat chest energy. What do you think that person is going to feel like? Do you think telling them "Oh, it's not flat chests that are bad, it's the energy" is going to suddenly make them feel better? Or are they going to associate their own boobs with negative emotions?

One of my biggest problems with supposed "allies" is that the moment they attack someone they don't like, it's back to the same body shaming insults, i.e ugly, bald, small penis, short. Do better.
