Quite a few children have died or been crippled because their parents refused common medical procedures because of their woo beliefs.
Jihadists have killed "infidels" because their religious leaders have convinced them it is their ticket to heaven.
Jim Jones led hundreds to their death with his particular brand of woo.
Televangelists pray on and fleece many who can not afford the donations they are convinced they need to send in.
