I cannot buy the argument that Christians are being persecuted in this country. Maybe by bloggers but certainly in no meaningful way. It seems to me that a lot of them think the 1st amendment extends beyond what it really protects. And the supposed small government conservatives need big government to push their morality agenda, go figure.
There is a difference between having rights infringed and persecution. I reserve the latter for truly punitive measures enacted by the State, such as fines, imprisonment, death, etc. There are many instances of rights being infringed, that I would not raise to the level of persecution. That said, there have been some very high-profile instances of actual persecution, including ruinous fines for a business that chose not to enter into a contractual relationship to bake cupcakes for a gay wedding, because of sincerely held religious beliefs.
