Hi everyone,
Have you ever watched a show on youtube called 'the atheist experience'? I'm not an atheist myself, more an agnostic/grudging and weak believer, but the show involves phone-in discussions between atheists and others, who often have a Christian fundamentalist mindset similar to that found within JWs. It provokes thought and can be quite entertaining! Most of the good points come from the atheists it has to be said :)
Here's a link if you're interested:
