psycho- 

A person who, or organization that, is so obsessed with something that they believe it to be the only right/correct/proper/acceptable thing, believes that their way is never wrong nor does anything wrong, believes all other ways are wrong/evil/misguided/unacceptable and seeks to shove their belief down your throat because they believe you are in need of being educated, converted, saved, etc. They are always close-minded and unable to think for themselves. They simply follow and try to spread whatever screwed-up ideology they were too weak-minded to save themselves from.
