Here's a good one for your favourite theists antagonist,
Can you name one good act that person of faith or religion has or could perform that an atheists could not.
Can you name one bad act that a religious person could perform, that a person who did not share their faith could not.
The first one is impossible, yet the second is easy. Blood transfusions anyone?
The people on this site that defend Christianity are making sure that groups like the JW's are able to survive because they defend making statements based on faith and attack those who criticize religion. I encourage all you latent former JW's still hanging on to some remnant of religion to contemplate this and take the bold step to realize that it was not just a few incidental doctrines that the JW's were wrong about, but the whole concept of god itself.
Contact me through a personal message and I will tell you how you can make a difference by helping to create an environment where groups like the one we escaped from cannot form again.
Together we can make a difference, together we can make the world a better place.
