Call yourself what you want though, It just seems to most people to mean "I'm an atheist, but not like those atheists, because I will pretend to take your invisible unicorn story seriously. I can't KNOW you are lying after all, as I don't believe in inference or the scientific method"
The real problem of evil is as follows. If god is all knowing, and can know the future, then the future is predetermined. If the future is predetermined then we have no real ability to perform moral actions, right or wrong (free will). Therefore we are potentially predetermined to eternal torture, and life has no meaning. If we do have free will, a god could not possibly be all knowing.
Of course, even the idea of a creator god is not worthwhile. If the universe is too complicated to come into existence by itself, it must instead have been made by something of similar complexity... then how was that god made? If that god can have always existed why not the universe, etc etc.
