Is there some moral precept that you just can't spit out?
I have no desire to kill anyone, even if attacked. I would rather try to defend myself with whatever non-lethal means available to me at the time.
And if you had your 'druthers', you'd make this same choice for everyone. Tell that to the 120 lb woman facing a 200 lb rapist. Or the 60 year old man facing am 18 year old thug. Or the guy with a bad back.
Free hint: it's not all about you, or me. It's all those pesky individuals who can't just weigh anchor and sail off to somewhere else.
