I'm sorry, I haven't read all of the posts, but I like the fact than MN isn't overly regulated/monitored/nannystated. I think pretty much all threads should be left to run their course.
There are lots of posters and many of us are able to run a thread into the ground if it's unsavory.
I understand why the Mums (& maybe some Dads but I haven't seen any) get utterly fed up of defending their children with SN and why they sometimes feel isolated, but honestly it does act as an education to some people. Other times you just need to hit the 'hide' button.
There is something that goes on here a LOT that really upsets me, sometimes I have a go, sometimes I try to reply with a well thought out post, sometimes I hit the 'hide' button and no matter how much it upsets me t see it there - I still wouldn't want MNHQ to 'pull it' because a) it's my issue not everyones issue and b) occasionally people learn something and c) I don't want to be on a site that is heavily monitored and full of restricitons.
I think it's also like buying an orange car, before you did it there weren't any on the road, now you have one the road is full of them - we see things that we are 'in tune' with so there seem to be more of them.
