I just spent the better part of a day being thoroughly entertained by a number of anti-Scientology websites.
The best source, I would reckon is Operation Clambake at [www.xenu.net
Then, Mark Bunker's blog at [xenutv.wordpress.com
] has some superb material.
Also, if you like videos, take a look at Xenu TV at [www.xenutv.com
Included on the website are some other videos under General Interest. Also, you will see what Scientologists are truly about in some remarkable videos featuring Mark Bunker while he worked for the Lisa McPherson Trust.
Seeing this stuff on video really brings out how bizarre this dangerous cult is.
Obviously, Rick Ross has a superb section on Scientology too at [www.culteducation.com
