I don't see what everyone's so upset for. That same article says that the federal government considers all such laws null and void, and unless I'm mistaken, federal law trumps state law if there is a dispute.
And at the same time, christians complain about being criticized about their beliefs and claim that their religion is being discriminated against.
WOW I WONDER WHY

This particular case is hardly discrimination against us. If anything, keeping that law in place would be discrimination
against everyone else. I am a Christian, and I can certainly understand that such a law is outdated in an age where atheism (or, rather, non-Christian belief in general) is much more prominent than it was back then.
