You think only believers have left? You're sadly mistaken. Intellectual people don't usually feel the need to ridicule either people or ideas. Pseudo intellectuals, that's another story.
I agree. I sometimes feel the atmosphere here is very negative, and I do think of leaving. I do stay in the end, but I don't usually go into certain topics, and I am sure many others have left for this reason. I do not get the attitude of some posters, and I am an atheist.
Most of us here were obviously JWs at one time, so why ridicule others for believing in God as you once did? You have learned critical thinking skills and are an Atheist now, good for you. Maybe others have not been out as long as you, or not had exposure to critical thinking as much as you, or have your intelligence. Does that make it OK to use your superior knowledge to ridicule them?
If your intent is to change hearts and minds by this, then you have failed, imo. If your intent is to show off your superior knowledge, belittle others and so feel good about yourself, then yes, you have succeeded. It's easy to go for the cheap put down, harder to understand, feel empathy, and maybe help others to learn something, if not the poster then those who may be lurking.
I get it, some believers are annoying, many have used tired arguments that have been used by others, and they aren't really interested in meaningful discussion. But for every one of these there are ten others who believe in God, but won't post or even stay and read the comments because you made them feel unwelcome here. I am not totally innocent in this, there are posters that push my buttons as well, but I try to be better than that.
I am not aiming ths at any one poster, I like most people here and think they have good intentions, but I do think some comments cross a line. It's not something unique to this board, it seems to be an internet staple these days, last night we had a flame war on Next Door (a neighbor to neighbor social network). But please keep in mind many readers here have recently left an abusive religion, they may be still recovering from this, they don't need to be made to feel stupid because they still believe in God.
