This just goes to show that the Internet has something for everyone. Click on over to Flush a Holy Book.com
and you can do a virtual Gitmo on the religious tract of your choice. I suppose this site will appeal to atheists, bigots and people who just approve of a little faith-based humiliation (not to imply that those are mutually exclusive groups—can you imagine the Venn diagram?).
At current count, the Bible is the most flushed book, leading the Qu'ran in the #2 slot by a 2-1 margin. Guru Granth Sahib, the Sikh holy book, is the least flushed religious document. Potentially because most people are not aware that it exists.
