Nothing is true for all atheists, except that they don't believe in gods. Atheists come in all stripes of political belief, cognitive ability, nationality, ethnicity, gender, age, whatever. Knowing that someone is an atheist tells you nothing else about them. Any judgement on someone's character, honesty, criminality, intelligence or responsibility that's based purely on the fact that they are an atheist, will be unsound.. Unlike being a believer, being a non-believer does not have implications on how other aspects of one's life are conducted. The dichotomy between believer and non-believer is not symmetrical.
