Well, lets take a good, hard look at what your saying;
Most 120 lb person (man or woman) would have a very tough time defeating a 250lb criminal. For those who argue otherwise, next time when you go to a competition, ask to be matched against someone above your division
Well here you are basing your opinon by rules of competition. Which are, as I and others have said is unrealistic. A 120 lbs women in a boxing match with a 250 lbs man
probably wouldn't fare well. But that has rules, referee and protective equipment. Thats not real life my friend nor is it the meat of my comment.
But in the case of 120lb woman against a 250lb psychopath? That is like YOU going up against a Sumo wrestler
Really???

I would take that bet. You see, your trapped into fighting the same fight mentality. If I were to fight a sumo wrestler....I wouldn't be wrestling him. Would I do well? Basing this fictional encounter with a real life event I would say better than average

Why? Well probably because I am 6' and about 170 lbs and the biggest enemy I have faced was 6'8 and weighed 380 lbs. He was a very violent and uncooperative felon and very intent on hurting me. One well placed knee spike and a shoulder lock persuaded him to discontinue his rude behavior. I don't have a big 'S' on my chest, but your fictional encounter doesn't cause me to lose sleep. I does reveal to me that you seemed to be trapped into a tournament mind set. I find this dangerous to yourself.
. Most MA instruction/lesson that the typical 120lb housewife get, IS NOT sufficient to equip her to defeat a 250lb criminal. I would laugh at those McDojo lessons focusing on throwing your attackers around.
I don't recall anyone mentioning McDojo training for our young lady.....
It is criminal to sell them this false sense of security and the big lie that criminals are so stupid as to stand there and let you do all your neat tricks that you play around in the safety of your dojo
Again, I don't think anyone has mentioned the method of training for our young lady. I don't have any 'neat' tricks nor do we teach on static, non-resisting targets. And since I have had a young female student, 5' tall defend herself MOST successfully against a would-be date rapist...AND since I work with a large number of female Deputies who reguarly are involved in uses-of-force against male inmates/prisoners and WIN I would have to consider your
opinion as uninformed and perhaps a bit testosterone laden.
Given proper training a woman with her wits about her can protect herself from grievace harm. It does not, and should not take great strength to correctly utilize a technique or tactic that is appropriate to the situation.
Perhaps you should not put your limitations on others....it's not accurate or realistic to do so my friend.
