Except for when you make uninformed claims about others, then try to make it their obligation to disprove them. Then your ability to contribute is severely limited by your tactics.The self defense I have engaged in have have been slobber knocker matches. And so some training that vaguely reflects that gives me the best chance of being successful.
So the usual narrative is essentially inescapable.
Now people can sell self defense however they want but without the essential elements of training with real resistance. Your slobber knocker training, It just isn't going to be a very good product.
That is why when I ask for a video of whatever people's crazy idea they think will work. I get some kind of excuse. Because they haven't tested it. And are trying to hide that fact.
And that is why I am useful in a technical discussion. Because instead of talking about techniques and methods I haven't used and don't understand. Or about self defense situations that I have read or heard about.
I have real practical experience and am not trying to scam anyone or promote some system I am selling.
I can wrestle on standing arm bars against duds without breaking people's arms by the way. There is a trick to it.
