My opposition to women in combat has always been very simple: When our daughters and wives to off to war with us, what's left to fight for at home?
In the interest of full disclosure, I've been out of the military for almost ten years now. Mrs. Doohickey is an Aeromedical tech in the USAF Reserve. She's really good at what she does, though she does struggle with lifting 70 lbs. over her head (a requirement for flight qualification). :)
That is an excellent point - what is left ot fight for when we ask our women to fight?
