You have to remember that for 3 centuries the proof of god consisted of:
What is more perfect a piece of furniture or the idea of that furniture. It is the furniture, because in that furniture you have not only the idea of the furniture, but the manifestation of it; therefore, since god is perfect, he must be real.

The key for me is to control the language, or at least prevent the religious from language manipulation which they do in order both to fool themselves and others. I do this intentionally. A simple example is never allowing a mono theist like a Christian to say the word God undefined. I insist they say 'my god', to force them to confront the reality that they choose to believe in one god rejecting all others, usually the one they were born into. This annoys the bejesus out of them. Control the language and you neutralize their use of bad history, invented mythology, absurb theology, unproven supernatural claims, and emotional blackmail and fear - - the basis of all religious arguments.

I hear them ramble and ramble on about it!
