There's a vast difference between someone breaking into your house with a shotgun and somebody cupping your balls at a rave. If you are uncomfortable with someone doing the latter to you, there are many ways of saying "Don't do that, I'm not comfortable with it" besides attacking them.
If not for your own sake then at least for others please do not be so quick as to prove your strength by physically harming them before warning them, even many animals are more civil than that.
people cup my balls at raves, all the time
