This poll at any rate is not very reliable. It does not take into account those people who have jobs and are too busy to be on the internet at all, or who haven't yet found JWD. It would not be uncommon for someone who is out of work to be spending time on the computer because they have more time to do so.
I also think that statement that it is regarding Apostates being unemployed deceiving. I think you could go to about any kind of discussion board and find the similiar responses. Not to mention it takes into account calling everyone who posted an apostate. Just because we post here does not necessarily mean we consider ourself one.
