I agree on what you say about "scientology", but there is one thing I'd like to ponder.
Any religion may be "outdated", but I would prefer the word "useless". For there is just one God, and he didn't create any religion. Jesus came to this world 2.005 years ago not to create a religion, but to teach us how to enter in a relationship with him and reach salvation through Him.
If you study the Bible (I'm assuming that you didn't for the majority of people who attacks christianity never read the Bible) you will be amazed how all this conspiracy theories that we talk about in this site are about to prove many of the biblical prophecies. 9/11, the road map, etc, they are pure biblical prophecies coming true.
Jesus is real, ALLELUIAH! :-D
