We all have met those kind of people. Religion, fundamental Christianity in particular, attracts those who are insecure and need a stick to punish others ("you are going to hell") and need a skirt to hide behind ("It is not me saying it, it is God").
As Dylan wrote
You got a lotta nerve
To say you are my friend
When I was down
You just stood there grinning
You got a lotta nerve
To say you got a helping hand to lend
You just want to be on
The side that’s winning
...
I wish that for just one time
You could stand inside my shoes
And just for that one moment
I could be you
Yes, I wish that for just one time
You could stand inside my shoes
You’d know what a drag it is
To see you
Song: Positively 4th Street
The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts - Bertran Russell.
