This article is the single best refutation of Christianity (at least from a non-Islamic perspective) that I've ever seen. Apart from it using that most egotistical of all words, "freethinker", I cannot find a single thing wrong with it. It would be a bit of a hassle to post the whole thing here because all of the spacing and formatting takes so long so I hope you don't mind if I just give the link. Besides, the background at the site is so pretty.
