I'm not surprised if you aren't aware of the issue,  but a little Googling will find some solid sources of information on the topic (you will have to get past the political and religious sites to find ones you trust, but the facts are there and not disputed).

Chem contraception can be used for many things, but the point here is to buy it for people -- that means you are encouraging people who are lower income to use a product they might not otherwise use.  The Obamas and Trumps of the world aren't worrying about the feds buying their bc pills.  The federal government subsidizing contraception for the poor is a way to reduce the birth rate in lower income households.  That's why the initiative is so popular, people like yourself can get free contraception as side effect of the law so you support it -- rich elitists support it because it keeps the number of poor people lower.  I'd rather shell out a few bucks for my own contraception than support that.  Wouldn't you?
