No way a random person is going to choke me out
Said the guy as he fell unconscious, oh yes I've had that before and I've choked quite a few guys out who said I couldn't, I've also made them submit, broke one guy's arm, accidently , when he wouldn't submit to a woman. And I'm not even that good, my friend Rosi is much much better, as is another friend Lisa they both teach men who will wait months to get into their seminars and classes. I know quite a lot of women who can choke and submit people without too much effort.
That sounds familiar but as I'm not getting into politics I'll refrain from saying more but it's clear you haven't met many of them, they are very good at what they do, well, it is the family business ( or perhaps you don't know why it's called BJJ), a high IQ has nothing to do with it.
compared to 90 percent of public with little to no training
Many muggers, thugs etc have no training in martial arts but will take you out every time. Relying on the fact you 'have training' but without practice is a dangerous road to take. Krav Maga can be great, depends on who is teaching, many places are rip offs these days but you still need the constant repetition of techniques to make them instinctive and can use them immediately if you are attacked.
Krav is a perfect starter system !!!
For whom and for what? It's an ill-educated statement to make as it means nothing,
