"You can't hit a girl"

I am sure you have heard the saying "you can't hit a girl". I HATE IT! It's inferring that we can't take care of ourselves. That we can not fight just because of our gender. You might not agree with me but that is what I think. I hate being told what I can and can't do, and this saying is telling you that you shouldn't hit a girl because they are to weak. And I hate being called weak.
