I made no claims regarding the benefits or necessity having or not having a particular worldview. I was commenting on her behavior.
Supporting Kim Davis is supporting the idea that individuals should be able to force their worldview onto others regardless of what the law says. She gets to be a "hero" because her worldview happens to coincide with your own. However, what if she were an atheist who refused to grant marriage licenses to Christians? Or if she were a hard-core feminist who believed that marriage was merely the enslavement of women and refused to grant licenses to any women. Would you support her "civil rights" then? Would you be like, "Way to go with the civil disobedience!!! We respect you living up to your conscience!" Naturally not.
I don't understand why people can't examine the underlying philosophy here and see how DANGEROUS it is to Christians. It's one thing to be all "rah, rah, yeah-civil-disobedience" when it's someone who espouses YOUR worldview. However, if you claim that she should have the power to allow or disallow marriage based on her own personal convictions, then you potentially set up a situation where ALL clerks EVERYWHERE can use their personal philosophies as a basis for granting marriage licenses. If this were the case, there would certainly be clerks who would refuse marriage licenses to Christians.
Asking her to obey the law within her job is NOT a violation of her religious liberties. Having or maintaining a particular job is not a RIGHT. If she finds that she cannot live up to her conscience and perform her job, then she needs to find another job.
As an aside, for YEARS she has provided marriage licenses to any number of immoral people--fornicators, drug dealers, thieves, liars, etc. I don't get why her conscience didn't bother her then, but apparently, it didn't. She seems to not have record of refusing to grant licenses to these people.
