I can see the arguments from both sides and the pros and cons associated with each. On one hand, it makes sense for employers to defend and practice their religious beliefs; after all, they are the business owner, therefore they make the decisions. In contrast, the employers would not be partaking in the use of contraception therefore how can they decide what other people can and cannot do? Additionally, a multitude of women cannot afford the expensive and most effective forms of birth control, so taking away free contraception could lead to an exponential increase in abortions, which what many conservatives are currently attempting to reduce.
