I have neither the time nor inclination to search out all the copious, bona fide examples of bias against Christians that have been reported over the years. If you do a search, you'll find them. Unfortunately, I can't presently find the article on the teacher reprimanded for saying grace silently, but I assure you it was an actual event, and I'll try to find it later. In the meantime, I will link to a few items regarding bias against Christianity and godliness that I found with a very cursory search. I'm uncertain as to the most recent developments in some of the resulting court cases, but the articles themselves serve to make my point: officials often greatly over-react to the first clause of the first amendment, while the second clause is essentially ignored. And that was my point.
