There is an old joke that goes like this...
I was walking across a bridge one day, and I saw a man standing on the edge, about to jump. I ran over and said: "Stop. Don't do it."
"Why shouldn't I?" he asked.
"Well, there's so much to live for!"
"Like what?"
"Are you religious?"
He said, "Yes."
I said, "Me too. Are you Christian or Buddhist?"
"Christian."
"Me too. Are you Catholic or Protestant?"
"Protestant."
"Me too. Are you Episcopalian or Baptist?"
"Baptist."
"Wow. Me too. Are you Baptist Church of God or Baptist Church of the Lord?"
"Baptist Church of God."
"Me too. Are you original Baptist Church of God, or are you Reformed Baptist Church of God?"
"Reformed Baptist Church of God."
"Me too. Are you Reformed Baptist Church of God, Reformation of 1879, or Reformed Baptist Church of God, Reformation of 1915?"
He said: "Reformed Baptist Church of God, Reformation of 1915."
I said: "Die, heretic scum," and pushed him off.
It's not really a funny joke, but rather one created to emphasize the tragedy of intolerance not between religions, but between sects of the same religion. And it
happens in real life:
Taliban terrorists stopped a convoy of minibuses traveling through western Afghanistan, questioned the passengers, then pulled all the Shiites into the road and shot them dead...
The Islamic militants then demanded to know which riders were Shiite. Fourteen were identified — including three women. The terrorists then bound their hands and led them off the bus and down the road.
The 14 were shot and killed.
The other passengers were allowed to continue their journey.
