As it is distracting from the crux of the matter, which is freedom of religion vs. freedom from religion.
Catholics believe all forms of birth control are a sin (not just morning-after pills). Therefore let's just discuss this form of medication since its use is less controversial.
What I believe that Catholics do not have the right to force their religious beliefs on others. In other words, if there is a non-Catholic employee at a Catholic institution, that person should have access to the same forms of contraception legally available to all other Americans. IMO...the employees are the ones being left out of the discussion. I don't believe the gov't should be force Catholics to do anything that is against their religion as long as (and this is the key distinction) those beliefs do not infringe on the rights and liberty of other Americans.
What I find funny is that Catholics are viewing this as a gov't infringing on freedom of religion. IMO, this is a case where the gov't has to protect non-Catholics from Catholic doctrines that could be harmful to them (for example, my wife takes birth control pills, but not to prevent conception. She takes them to prevent ovarian cysts that are a legit health risk).
But to get back to "abortive agents", let's say an employee of a Catholic facility is raped, and fears that the rapist may have impregnated her. I think her health care provider should be required to provide her access to morning-after pills. Do you disagree?
