A hard kick can do damage anywhere. That's why I specifically called out the comparison to a groin shot on a guy - if you can show me a woman completely incapacitated to the point of nearly vomiting from a touch as light as flicking the area, then yeah, I'll start accepting that there might be a comparison.
Besides, if it's just a matter of "same area, same damage," why do liver shots only happen on the right side of the body and not the left? Could it be, perhaps, that there's a sensitive organ there that accounts for the difference in pain?
Based on what? She's never been kicked in the balls. Can guys start comparing pain to how it feels when a woman is in labor?
Meanwhile, guys are in such pain from a low blow that they have to take a break despite the area being completely covered by a hard plastic cup. That's a level of sensitivity and pain women will never feel or comprehend.
