Something else that i found interesting about the list is that it is so universal that it can be applied to other cultures/ countries. That means that there are biological differences in personality or behavior that are pre-programmed in the genders. For example, "take it like a man" is something you will see in every culture. No one will ever say "take it like a woman."
The essay also goes on to say that other guys are policing and teaching younger guys how to behave. I don't see why the author had a problem with this. It makes sense guys are going to look up to guys and want to behave like them. How they behave on the other had is questionable.
