I agree that he should ultimately want less meat consumed, but how (as a mathematician), can you say his reasoning here is illogical?

He could say to his friend, "Do me a favor and don't eat meat for day.". And then if he doesn't eat meat himself he'll have reduced the amount of meat eaten for that day by one person. The problem is...

His friend will probably reply, "Uh, I don't think so.". So if his friend will only agree to go a day without meat so that his friend can eat meat, it's zero sum! Everybody wins!

My personal philosophy is that I did not claw my way to the top of the food chain to eat a bunch of lettuce! Gimme meat!
