Type a few words into the search field on Google's home page and the engine automatically returns a helpful list of popular, similar searches for the words you've typed in so far -- a convenient way to find the right information.
Enter "Christianity is" and you'll find results that, while offensive, at least indicate common discussions on the Internet. Likewise, type "Judaism is" and Google suggests other, potentially offensive searches such as "Judaism is false" and "Judaism is not a race."
But type "Islam is" into the search engine and Google's auto-results pane mysteriously vanishes, leading some to conclude that Google, whose mantra is "don't be evil," is censoring its search results.
An intriguing corollary: Google offers search suggestions for future tense queries as well. Ask "Christianity will" and Google suggests "Christianity will end, it will disappear," and "Christianity will end." Ask the same about Islam and Google notes that "Islam will dominate the world"
