"Almost all male U.S. citizens, and male immigrants living in the U.S., who are 18 through 25, are required to register with Selective Service. It's important to know that even though he is registered, a man will not automatically be inducted into the military. In a crisis requiring a draft, men would be called in sequence determined by random lottery number and year of birth. Then, they would be examined for mental, physical and moral fitness by the military before being deferred or exempted from military service or inducted into the Armed Forces."

So much for gender equality either, only men having to register.

CONSCIENTIOUS OBJECTORS
Men who would be classified as Conscientious Objectors if they were drafted must also register with Selective Service. If a draft begins and they are called, they would have the opportunity to file a claim for exemption from military service based upon their religious or moral objection to war.
so what is your point, exactly?
