if you add strength it is always going to even the odds against a stronger opponent alwaysBJJ does as good a job as I've seen of working around the size/strength disadvantage. Just adding strength isn't much help unless it actually evens the odds or gives you a strength advantage.
all the arts are based on using technique t increase effective strength, all of them run in to trouble if the guy is significantly stronger than you. Including BJJ. The skill levels require to overcome a significant strength disadvantage exist,,, but not in the vast majority of people who practise an art.
To tell people that any art will reduce their risk of sexual assault with out explain the shortcomings is misleading
