This made me remember the story that early Nazi Party was full of government spies tasked in destroying Nazi Party, Hitler being one of them. They were supposed to act like true Nazi and infiltrate them heavily until they had enough information to dismantle it... but the spies quickly overran real members (seemly when Hitler and others were sent, the party had 15 members or so... and for a while the party had more spies in it than real members), the spies, that weren't "real Nazi", while trying to blend in introduced more and more ludicrous ideas and ended convincing people for real, seemly including themselves...
