I'm not sure I've heard anyone say they want to get rid of all parents on GC. Sure, some people have less tolerance for parents sharing their kid's stories than others, but such is message board life. I have little tolerance for a lot of stuff. I'm sure there are people who have little tolerance for
my relatively dispassionate posts.

I sincerely doubt everyone will ever come to a consensus, but what I'm reading above is that the majority of posters who have replied have little problem with parents who are merely talking about their kids, but not trying to control their kids. Seems like the effort to control and smother are the more defining characteristics. And yes, people on GC have a real distaste for parents venting here. For good or ill, coming on this site and
complaining about your kid's rush results is a recipe for disaster.
Would I be absolutely mortified if my parents were talking about my personal life on a message board? Yes. Do I cringe every time I see a parent doing such? A little. But, if their kids know they are sharing online and don't have a problem with it, then neither do it. I don't think it's right for a parent to be dishing about their kids when the kids are unaware of it, but that doesn't mean my opinion should dictate others' actions.
If we all left the site when someone didn't care for us, or if being disliked was a bannable offense, this would be a pretty dead board.
