It's not uncommon. Little girl in a Florida kindergarten told that praying is not good by lunch teacher after praying for her food.
No, I'm not surprise by it. I am bringing this up because I am beginning to see a pattern, that the anti-Christian movements seems to be obvious only in the Bible-Belt arena, while liberal cities rarely see this kind of cases.
One sees the need to fight against the fundamentalists, while the other tries to not mind anybody else's business (that means, no greeting, no preaching, no helping, no nothing).
My conclusion is that the hostility is there. It shows that if Christians were to speak up, Satan will come to work. His job is already done, when Christians do nothing.
