Elton John claims that we ough to ban religion altogether. Good idea or bad?
Bad idea. That would only force the religious to form underground movements and become even more self-righteous over their persecution. It's bad enough when Christians complain about the removal of the ten commandments from government buildings as persecution. A ban could cause a civil war. Besides, you can't force enlightenment.
And, incidentally, do you think it contributes to making people hateful?
Some use it to reinforce their prejudices (average fundamentalist) some for peace (average Quaker).
