I volunteered for service. I was not drafted. I do not believe women should be drafted. Therefore, no contradiction.
The main reason for a draft is to fill combat billets. IMO, women should not serve in combat, including certain ships and aircraft. Therefore, they should not be drafted. That has been my position for many years, based on research that I did for a paper, common sense, and my personal experience.
Since I don't believe that women should be drafted, there is no reason to register them with Selective Service.
So? What's your point?
I believe the purpose of the military is to defend our country thru military might, and the threat of military force. It is not the purpose of the military to provide equal opportunity employment to anyone who desires it. Women can, and have, served bravely and nobly over the years. However, I believe they can serve best in non-combat roles. Would that limit promotions and career opportunities for women in the military? Probably. But like I said, the military doesn't exist to meet the needs of individual career goals.
Because, in general, men are more physically suited for combat roles.
An expectant father can still physically perform combat duties. An expectant mother cannot.
The military doesn't want "violent" men either. Maybe you mean disciplined aggression?
It must be something new. During my 24 years in the Navy/Naval Reserve, I never heard about the military having an ability to "regulate their women soldiers' periods". If that is true, I wonder how so many military women become pregnant while in combat zones, and on board ships.
Equal pay and fair treatment in the work place is an issue separate from military service. I do believe women should be treated fairly in the service, and when a man and woman are performing the same services in the military, and are the same rate/rank, with the same number of years seniority, then they should get the same pay and benefits.
Our country should not depend on women to fulfill its combat billet requirements. Those should be filled by men. If our country ever gets to the point where it depends on women to satisfy our combat needs, then we will truly be in deep trouble. Other nations view that as a weakness, and look down on countries that use their women in combat roles.
Just "because 55% of Americans are female" isn't a very convincing argument for drafting women.
