Ok may I say a little?
First of all I'm completely neutral about this topic, and I'm trying to consider all the facts in a objective way.
the first hot point in this debate is whether or not women are capable of all military jobs. intellectually, women in military score higher than men. physically, women are not as strong as men through out history, but during resent years women's athletic performances are getting closer and closer to men. Also considering the environment most women grow in, we can see that culture demands women to be less muscular. Another fact is that as modern warfares and strategies involves more and more high technology, body strength is getting less and less important.
The second hot point is whether it is appropriate for women to kill or get killed in the battle field. Should women be gentle and less agressive than men? Their hormones do have some effect on agressiveness. However our culture demands women to be nurturers rather than killers since they have adopted the task of bearing children for a long time. As far as the willingness of suffering injury, I would like to wait till some ladies posted their opinions
The third hot point is the equality between men and women. Chivalry values require men to take care of women, the reason is women are thought to be WEAKER than men. So chivalry value is based on men's expectation, not women's. Again, our culture specifies such a standard that men should open doors and pay for purchases, therefore such actions are social NORMS rather than personal desires.
