'Logic'? Ahem.

 I'm not sure what you mean by 'male role' or 'female role'? Obviously, only women can breast feed, but that does not stop a father from feeding the baby with a bottle (or burping it or changing the diaper or singing it a lullaby). I think my question is valid -- what are you trying to prevent me from doing? Yeah, there are very few women lumberjacks and fire fighters, but these days, more and more women cab drivers.  Recently when I was in the hospital, there were plenty of male nurses and male aides, and they are excellent! So what is it I should not do that is strictly a male role? These days it is too late for me to do lots of things, and I would never have been suited to be a priest, nor did I ever want to be a priest, but I applaud women who are qualified for that and do it

Chauvinistic structures in religion are not holy (promoting wholeness) and should be changed

Tony, if we copied vertebrates or invertebrates as you suggest, there would be no religion at all
