The more you talk, the less you say.

Given the concept "sometimes it’s best for a man to hit his woman to get her to behave", you generalised the words "man", "woman", and "behave" to "someone", "someone" and "do something", and ignored the word "his" altogether. Now you're generalising "best" to mean serving to get whatever the first someone wants.

This reduces the whole matter to fatuity: the optimal tactic to get people to act according to one's goals is whatever will achieve those goals. Duh. The original question was about certain specific goals and specific ways of getting them.
