I am using an extreme title here to illustrate a point. We have a searcher come to the Google Webmaster Help forums and complain about the search results for a search on Google for [christianity is]. The results are mostly informational but you have a few results which are negative. I cropped this image to show only some of the negative-like results:
The person said, "I have never been so mad in my life. We have enough problems in the United States without Google slamming Christianity!"
When will people learn that this is not Google slamming Christianity? Well, maybe what set this person off is that Google wouldn't say Merry Christmas on Christmas? But still, these are the Google search results. Brin, Page and Schmidt aren't sitting down and saying, hmm - I hate Christians and I want to place these results there simply to tick them off.
There are just so many cases like this, for all religions. It comes down to education, which is a hard thing to do.
