It's not their faith telling them they are abortifacients, It is the US Government Department of Health and Human Services. HHS says the 2 IUDs in question and the morning/week after pills in question keep a fertilized egg from implanting in the uterus. Their faith says that life begins at conception, so being force to pay for something that keeps that life from implanting in the uterus is a violation of their religious belief.
So basically, you're just saying what I'm saying, "It's their faith that tells them these are abortifacients."
Further, when you talk about the "they" in "their religious beliefs", you are not talking about individuals, but a corporation. Now, we can argue whether or not corporations are people, my friend, but I'm pretty sure you will agree that "Inc" does not have religious beliefs.
As you can clearly see from the National Review article (and the National Review is the mothership for anti-abortion types), this is NOT about abortifacients, but about absolutely anything that someone can say violates their religious beliefs. And if you recall your history, you will note that at one time people found religious justification for owning slaves, refusing to serve blacks, gays, Catholics and Jews.
That's why Hobby Lobby is this era's Plessy v Ferguson. It will go down as one of those decisions about which people will someday say, "That wrong-headed case was decided during the bad old days". And not because of anything having to do with abortion.
I'm sure there were people back during Plessy, that made rational-sounding arguments just like yours for why segregating the races was God's will.
