"Religious liberty"

From today's CNN:

Washington (CNN) -- The high-stakes fight over implementing parts of the troubled healthcare reform law will move to the U.S. Supreme Court in coming months, in a dispute involving coverage for contraceptives and "religious liberty."

I find it interesting (and revealing) that CNN finds it necessary to put the concept of religious liberty in quotes, as if it's some anomaly that cannot really exist or be explained.
