Why would someone disagree that "real men don't cry?" Explain

A reason is that every single human being cries, no matter what gender or what age. How would a man feel if their mother passed away? They would feel an emotion to cry, release their sadness in some way. And that way, the most normal way, is to cry. Every man - I guarantee has cried at some occasion. Since that's the way the body works, all humans will cry no matter what gender they are. And there is also no such thing as real men. Just because a man will not step up to fight someone or will avoid another man it does not mean they are not a real man. And just by common sense there is no such thing as real men all men are real mean!
