There are people who genuinely believe that you need a belief system in order to make you inherently 'good'. Street pastors often charge me with being 'unhappy' because to them I can't be anything but if I don't subscribe to their beliefs.
Is not atheism a belief system? I've certainly encountered atheists who believe that those who advocate theistic beliefs are inherently 'bad' and can't help but wonder why anyone with an iota of sense would subscribe to such 'unhappy' alternatives to the 'truth' of atheism. Unfortunately, it seems to be a rule that with any belief system, there will be those who denigrate those who believe otherwise.
Depends on whether you define atheism as "believes there is no God" or use the atheism/secular humanism combination that is so prominent these days.
