I have applied the RNC countless times. I have never killed anyone with it, nor have I ever tried to kill someone with it.How is a rear naked choke not trying to kill someone?
While I will grant that fighting outside a competitive event carries a greater potential for death or serious injury than within, and it's certainly something to be aware of, the notion that every single encounter is a no-holds-barred fight-to-the-death strikes me as more than a little melodramatic.
