123everton - “In answer to your question, no I couldn't, it's a stupid question [Can you give me one example of a good deed done by a religious person that could not be done by an atheist?].”
No it isn't. It's a very sensible question because it makes you ask the alternative question – or didn't you consider that with your myopically simplistic perspective?
The alternative question being, “Can you think of an abhorrent deed the can and is carried out by a religious person that could not be done by an atheist?”
Personally, I can think of a great many. Male and female genital mutilation perhaps or murdering people who don't agree with your belief that your particular God should never be painted, drawn or depicted visually in any way? Or how about killing people for even having the temerity to question your beliefs?
All of the above abhorrent acts are permissible if you believe in the Islamic God. These religious pronouncements are codified in the Koran and are actively encouraged in Islamic controlled countries such as Saudi Arabia, Iran, Pakistan, etc.
