vooke,
I know at the back of your mind you might be thinking this is about anti-Christian society. But for many in America, especially minorities, it really is about race. There is a large section of the white polity that has never made peace with the civil rights victories. One could argue they have never made peace with the end of slavery where blacks were merely freed but not guaranteed the same rights as whites. Christianity
really is not under siege in the US. If you've spent some time in the US, you can always pick up those latent vibes in these controversies. You grant them rein to discriminate gays, and it's on to the main target, blacks.
In the story I have linked to, a GOP state representative accidentally lets the cat out of the bag by saying business should be free to discriminate against blacks. Of course he frames it in a manner to suggest that he is for the freedom of the business owner, where this freedom is apparently curtailed by the need to treat customers with equality.
"It is his business," Clark wrote in a comment. "He should have the opportunity to run his business the way he wants. If he wants to turn away people of color, then [that's] his choice."
