As things stand today, thanks to cloning, men are not necessary anymore for the preservation of the human race. Women can do anything, from leading countries to driving trucks. Let's leave men their one thing they are exclusively good at. Heavy lifting. 
Joke aside, I do not have a problem allowing men to do things like heavy lifting, opening doors, and offering their hand when I am stepping down a bus or ladder.
You know it's love when the pain of being apart is greater than the pain of being together.
