Lostathome - Some of the benefits to the world - GWAR Devo The Dead Milkmen, Gilbert Sheldon of the Furry Freak Brothers fame, Winston Smith the Dead Kennedy's visual artist, Timothy Leary, William Burroughs were a few card carrying members.
When I was really at the end of my tether, there have been times when the support group has kept me in the world. Their bizarre humour and kind encouragement has kept many desperate lonely misfits going, so I think that's of some benefit. Other churches alienated me or turned me away when I needed help.
The propaganda hassles its followers for money constantly, but many people in the Church are in a marginal economic bracket and we don't enforce collection like Scientologists or Catholics. I paid my $30 membership once only, and only because they deserved it - they gave me a good laugh when I seriously wanted to die. I've never been heavied for money ever, and they still talk to me. I even get an impression that they appreciate my social / intellectual contributions. They're good wacky fun. To me, anyway.
