Sorry, Mary. English is certainly not my mother tongue, so maybe I didn't make myself clear...
I think so too particularly with your tack line:
"The goal is to protect your attacker, then yourself!" --MS
"Oh, really. Me says that's BS!" --AV
The way I read MS's statement is that the GOAL of training is to acquire the skillset whereby one could protect oneself without inflicting (serious) injury to the attacker. The GOAL has no time bar. If the GOAL is BS, then why bother stepping on the mats.
