Why do you think atheists on Fluther ask so many theological questions?

There are many, many questions here on Fluther regarding God and theology that are asked by self-professed atheists. Why do you think it is that so many folks who are very vocal in sharing their atheism ask so many questions about the belief it God? Many of these people are regular users so I am not convinced trolling is the only explanation. I am also not convinced that it is merely to gain insight into the thinking of theists because much of the time when theists share their opinions there seems to be a concerted effort to change these opinions.

I am not interested in a theist versus atheist discussion, I am interested in hearing opinions as to what might be behind this phenomenon.
