Your entire statement assumes that male and female stereotypes are truthful when there is no evidence they are anything but harmful and false.  Even science does not back women and men think differently or want different things based on their sex.  

There is no such thing as maleness outside of have male sex organs or not.  

You have just proven my point.  These groups only come together to try and make men and women feel like they are divided when they are not meant to be.  God tells us men and women are both equally man, not a set of complimentary two different creations.  One creation - both male and female God named Man.  

Fraternities and Sororities have many problems associated with them.  Sexism and rape being high on the list.  So no thanks.  

Other than sexism there is no need to divide any group by sex.  Just like there is no need to express a group's whiteness by excluding blacks.  

There is no need for any charity to be gender exclusive and I don't support it.
