As I said before it isn't that brutal and not that powerful, there's a lot of bogus self defence out there aimed at women, much of it is frankly rubbish. 'Soft' arts are rarely soft though, they may look like it when done by experts but like a lot of things they make it look easy.
As for 'brah'
not all on here are men, me for example so I know what I'm talking about when it comes to women's SD, so much is aimed at us, 'eye gouges' well they'll work is your assailant is standing still with his hands down by his side and his legs tied! Much better, easier techniques to use. The main focus for women are techniques that enable them to escape ie hit and run.
If I had a pound for every time someone has said, 'grab their nuts' I would be rich but really it's very rare you'd get a chance to do that, most men will be very aware of their tender anatomy and stand sideways on etc to protect themselves.
There are good SD courses for women, but as the subject encompasses more than 'brutal' techniques you do have to look carefully at what you do.
