scifag

Reference to Scientologists. Especially those who are the types to write into papers or comment on web sites spewing their cultish propaganda.

scifag: "Anonymous" has publicly proclaimed its guiding materials to be the Communist Manifesto and Mein Kampf. Quite obviously, this group is not just anti-Scientology, it is anti-freedom of religion, anti-free speech and anti-American.
