Nobody ever left a crevo thread mad at someone they weren't mad at before it started?
Are you suggesting that one can not harbor animosity unless they first have someone specific upon whom they objectify their animosity?
Yes, certainly they have. Perhaps a more interesting question is whether the discussions on the crevo threads change the minds of any of the participants. I'm unable to think of an example of where that ever occurred.
I will concede that it's quite possible that minds have been changed among those who read and don't participate, but that's pretty hard to quantify.
What we do see is animosity building shortly after the original article or post has been made, and then the thread becomes a generic discussion about evolution in general, often only vaguely related to the thread post.
I'm not sure it's all that helpful to the participants, because it quickly becomes a case of posters on one side patting other teammates on the back while taking turns attacking the other side.
Nothing ever gets resolved on the thread, especially since those who try to find common ground are either ignored or are attacked by both sides.
The thread finally ends when both sides tire of the battle for the moment.
