A Bleating Ewe, Raising Little Sheep
Go ahead and try to breed little eunuchs, lady. I can only hope that they'll take the right lessons from real men (where the hell is your husband in all this?) at some point in their lives to grow into citizens, not subjects. She ought to be encouraging the sort of boyhood play that pits a good guy against a bad guy, where the bad guy loses and the innocents are protected. That's the way to channel the aggression.
