What? If there's someone walking around punching a bunch of people in the face and I'm very anti-face-punching, 100% I'm going to go against my principles of not punching the one time to punch that person in the face. They should then, hopefully, understand what their actions were doing to those around them and develop a sense of empathy.

I feel this is as justified as outing Republican politicians who have spent their days in congress making anti-LGBT+ legislation and spending their evenings with rentboys.
