"But with all the mysticism and intrigue of martial arts, it’s sometimes hard to tell if the Karate Master you’re speaking with is a passionate hobbyist or a delusional douchebag. The easiest way to tell is how much he explains his fighting style before you’ve asked. If a guy tells you he takes krav maga and he’s done talking about it, he’s a normal person who enjoys krav maga. If he tells you he trains in krav maga and immediately describes the situations where he could use it like the Israeli commandos who invented it because they needed a fighting style that worked, you should feel safe using a punch to get him to shut up."
