Basically, a company was allowed to refuse abortion coverage in their health insurance due to the CEO's religious beliefs on that subject. So now a group of Satanists are trying to do the same thing, except forcing the company to allow abortions due to the individual's religious beliefs.
Basically, it's a situation of "the road goes both ways." They've done other similar things, too, like giving a support rally for a bill allowing children to pray in school since that also means the children can pray to Satan.
I'm glad these people exist. They're providing women an option to choose an abortion or other rights taken from them from other people's religious views. The USA was founded on religious freedom, which I always interpreted as freedom from being forced to follow other people's religions. And there are several laws across the states that violate that, yet are going unchallenged through a taste of their own medicine.
