Taking that analogy a little further, do committed aeromodellers think that non-aeromodellers are bad people, and totally wrong in all their thinking? Do they think that non-aeromodellers are a specific group of people connected by a single philosophy - the determination to prove that aeromodelling is wrong?

No, they accept that some people are interested in model aeroplanes but others are not. If only theists could have a similar view of non-theists.

Some posters here are still very confused about what atheist means. First you have to know what theist means.
