Aside from practical considerations, which are numerous, there is the ethical consideration that men are supposed to be the protectors of women. That is the way it ought to be, and women serving in a combat role is a subversion of the order that God created. All this is doing is destroying the wonderful diversity (ironic from the liberals who love "diversity") that existed between the sexes that resulted in a healthy interest of trying to understand the other better. Now, we are becoming one giant androgynous society without men or women. I have no idea why one would want to live in such a world, but in seems to be the way we are going.
