These arguments amuse me. "Men are more mechanical", "turn women into men", "men are stronger", "who will take care of the children", blah blah blah. First let me just address that last part. Why can't men take care of their children? By putting child rearing entirely upon women you pretty much say that men are incompetent as fathers and are incapable imbeciles when it comes to raising their own children. Quite the sexist thing to say against both genders.
Why I find all this so funny..I am a SAHM right now. By choice. In my past I have been an Avionics Tech in the Navy, an industrial electrician and mechanic in a factory, a machine operator in a production plant, and construction worker in the Seabees. With all that I have also had babies, breastfed, been a SAHM, and I have a weakness for bath stuff and lotions that all match. I can be "girly" at the same time I'm talking about how to fix a car. I can take a super bubbly bubble bath with candles burning after I get done weight lifting.
Women can do many things and still be women. Doing jobs that are considered "male dominated" doesn't make women more "manly" just as men working in more "female dominated" fields aren't more "womanly". Does a man being a nurse mean he is somehow "less" of a man? No. He's still a man. Just as a woman doing any job is still a woman.
Stop boxing people into ridiculous boxes that simply don't fit and are mislabeled.
