Can atheists convert theists?

[Godhead]

Why do some atheists (judging from a couple of the responses) feel the need to say that they aren't interested in converting theists, and then show signs of frustration when theists don't agree with them, in the form of resorting to ridicule? That's not very consistent. You should be honest and just say that you'd really like to convert theists, and that it frustrates you when you don't manage it. People don't just ridicule others merely for fun, they do so for a specific reasons, and in this case I believe it is out of frustration. And that of course begs the question, what do you feel you lose when others don't agree with you?
