Y'all are misunderstanding theists main reason for belief when you attack it's likelihood. They don't think God sounds likely, but that it's better to assume God exists so you can at least pretend one's happiness is justified; god gives hope and hopelessness is the enemy. That's the argument you'd need to undermine to deconvert people. I'm not articulate to do that, so I link someone who writes for a living instead. http://gretachristina.typepad.com/greta_christinas_weblog/2008/11/a-safe-place-to-land.html
Right, it would be easier to deconvert if you give some hope about the other side. An analogous idea at LW is leaving a line of retreat.
Note: for editing (italics, etc), there's a Help button on the lower right hand corner of the comment box.
I've often had half-finished LW post ideas and crossed them off for a number of reasons, mostly they were too rough or undeveloped and I didn't feel expert enough. Other people might worry their post would be judged harshly, or feel overwhelmed, or worried about topicality, or they just want some community input before adding it.
So: this is a special sort of open thread. Please post your unfinished ideas and sketches for LW posts here as comments, if you would like constructive critique, assistance and checking from people with more expertise, etc. Just pile them in without worrying too much. Ideas can be as short as a single sentence or as long as a finished post. Both subject and presentation are on topic in replies. Bad ideas should be mined for whatever good can be found in them. Good ideas should be poked with challenges to make them stronger. No being nasty!
