That's an interesting point. I'm going to have to think about that. But i'd like to say that this argument isn't just preaching to the choir. I've personally seen it work on getting people to stop supporting corporal punishment.

Maybe it is a leap in logic, but it's also a leap in logic that most people make. Most people do value non-violent solutions more than violent ones and they look down on people who lack patience, work ethic, creativity etc. I'm using this to my advantage and calling them out by letting them know they are being incompetent, lazy and/or sadistic (and by their own standards too). Though I'm doing it in a slightly more compassionate manner.

I guess I should say that this argument is for people that like to think of themselves as "caring." People who already accept the premise. I do think that's still a lot of people.
