Crosby Stllis & Nash had a song called Cathedral which kinda sums up the atrocities of religion. I believe it went something like this (picks up guitar and plays open G chord)

Open up the doors of the church and let me out of here
Too many people have died in the name of christ for anyone to heed the call
So many people have died in the name of christ that I can't believe it all
now I'm standing on a grave of a soldier that died in 1799
and the day he died it was a birthday, and I noticed it was mine

sorry, thats all I remember, cool tune though.
