Yeah, the ones that teach all those stupid advanced moves that 90% of the girls aren't going to remember or have the strength to pull off are pointless.
Years ago when I did karate we'd do self-defense classes for women every now and then. We'd teach them nasty shit they could actually do, like groin-kicks\knees, eye gouges, throat attacks, headbutts, certain bites, etc.
We also use to teach them a lot of psychological stuff, like making themselves seem smaller, more scared and more vulnerable than they really were so they could create opportunities to escape or go for the eyes, throat or groin.
All of this stuff borders on common sense and instinct so it's easier to remember in the heat of the moment, but it can all still be trained further.
Yeah, a girl ain't going to remember a fucking lapel choke or some shit when some dude has mounted her and is likely hitting her. They can remember how to poke out eyes, squeeze balls and bite easy enough. I love BJJ, but the nasty stuff is a million times more effective in a real fight situation anyway.
