I don't understand why you think that birth control should be a separate part of insurance coverage. No one is advocating paying for a woman's insurance premiums. They are just saying insurance coverage needs to include birth control. Why would you think that means you would pay for it? Twenty-seven states already require insurance coverage for birth control. The argument that only 50% of the population can pregnant is beside the point. Women's reproductive systems are not separate from the rest of their bodies. The hormones that chemical birth control influences to not just work on a woman's ovaries, and uterus. They bathe the entire body in hormone, the cause all kinds of other effects; some of which birth control pills also affect. Other prescription birth control includes IUDs, Norplant implants, diaphrams, and sterilization.
