advertising atheism on the sides of buses...good idea?

[Godhead]

Although I completely disagree with atheism, I don't see a problem with atheists letting their views be known, and maybe even doing so in the hope that others will become interested. Religious people have always tried to spread the word, I don't see why atheists can't do the same. However the best way to try and get others to agree with your view is to have a proper chat and answer questions rather than just putting up adverts. Then again I don't see why anyone would have any interest in going out of their way to have others agree with their view in the first place. But as far as the right to do so, there's no problem.
