Man's World

Someone reminded me that guys tend to call other guys by their last names, but call women by their first names.  Upon reflexion, I tend to agree.  If a woman finds herself being called by her last name, she is probably in a male world, or male culture, such as the military.  Why is all this?  Maybe it comes from guys competing with one another, so they create some distance by using last names.  They want to get "to" women, so they use first names, as an attempt to close whatever perceived gap guys see between the femal world and themselves.  What is your take on this?  In Chrsitian religion, when people are angry, they say "Christ."  When they feel more intimate with God, they say "Jesus" which is the first name, so to speak.  In recovery meeting, first names are always used.  It is more than an anonimity thing.
