A recurring theme on this forum is that Christians are evil & hypocritical. But how about atheists?

Considering the many criticisms here of Christians judging others and allegedly "trying to impose their views on others" [I thought that is what voters in a democracy do routinely?] as well as being intolerant bigots, that constant drumbeat led me to wonder: How did it happen that the atheists who regularly post these observations managed to escape such serious sins? What is it about being an atheist and critic of Christian that led to such a superior state of virtuous ethics and allegedly accurate essment of the flaws of others? (And doing this so well while avoiding all hypocrisy!) Help me to understand how these moral attainments were possible? And seeing how I'm unlikely to fall for the "superior thinking habits" argument -- after having read far too many R&S forum posts to be that gullible -- what possibly could be the reason for all of that real (or imagined) superiority?
