Is this Just Self-Defence?

[Emithith]

I believe that it is a far more serious case when it is a Male vs. two Females-- Females definitely have less strength, and pose less of a problem-- than two Males vs. one Female. It is Sexist, for sure, but it isn't without reason.

I do agree that the male went way too far by bludgeoning them. That's coldhearted.
Besides, you could probably just threaten them off and they wouldn't stay for very long.
