When Did Expressing Doubt About God Become a "Negative" Attack Message?

This blog post is in response to another blogger's article on the American Humanist Association's recent ad campaign.

For the life of me, I cannot see why an ad campaign that suggests there is no need to believe in god or gods is somehow a negative attack message.

When did an honest expression of doubt and skepticism become an expression of religious intolerance in the eyes of some believers?

This ad is critical of traditional religious belief. But we should not live in a society where we engage in religious "idolatry" where honest questioning is discouraged.

Any idea (religious or non-religious) must be able to withstand criticism.

Any idea that cannot withstand critical analysis should be rejected or modified.
