Atheists are emotionally stronger than theists

[robvalue]

How often do atheists seek out theists to try to tell them how wrong they are? How does this compare to theists doing the same to atheists? I'd be pretty confident in saying atheists do it less, which suggests to me that atheists are more comfortable with their beliefs and those of others. Is this emotional strength, of a sort?

(I'm not saying no atheists do this. Of course they do. There will always be argumentative and confrontational types.)
