A common assumption when it comes to the issue of gender and rights is that women are in need of rights, and men already enjoy full legal rights. In actual fact, women, at least in America, enjoy more legal rights than men. Women, for example, are legally protected from being drafted into war, from infant genital cutting and from being forced into parenting children they do not want. Men have no legal protection from any of those things.
Every 18 year old man in the US must register for Selective Service, and failing to do so is a felony offence which carries the penalty of disenfranchisement in some states. Men cannot vote without agreeing to die, where that penalty is in effect. Women are enfranchised by the simple act of turning 18, and are thus empowered to elect the leadership that can legally compel men to war while protecting women from the same fate.
