I think that's it as well Pingfah. Although you are secure yourself, imagine being a little less self assured and walking past church signs, facing doorstep converters etc telling you 'repent or die' and seeing nothing at all from your own side saying 'hey, you know what? your beleifs are just as valid.'
I guess so yes.
Still, if they were expecting that religious people just reading the message "There is probably no God, now stop worrying and enjoy your life" to understand that it was aimed at atheists and agnostics and not proselytising at them, then that's a little naive. They MUST have known it would stir this controversy.
The double standard it has revealed in the attitudes of
some Christians is really quite delicious though. I find it hard to believe that wasn't at least a secondary aim.
