You would often see their cringeworthy adverts say something like this "Self defense program for women", "women empowered" and the way they say it works for women. It's well known self defense is completely useless and won't work against men so why do they do this? Wouldn't this marketing scam tarnish their reputation? Is it better of saying "women only" class instead? I have not seen one boxing, wrestling and other combat sport gym does that but it's so popular in BJJ.
