Need an outlet for your anger? Sometimes have an uncontrollable itch to hit something? Get into boxing! Or get a girlfriend. Same thing.
I feel very uncomfortable when I hear about violence against women. Do you think that women are an appropriate outlet for letting out your anger?
It's like saying: you're hot, you're the same as my smothering flame.
Joking about violence against women isn't right as they are just like everyone else and deserve to be kept safe and free from harm. Spreading ideas about domestic abuse normalizes it and trivializes the harm that it does to women. Instead of making jokes, try to be an ally for women who have been abused as it is something that can always potentially occur to women in your friends and family group.
