I haven't ventured off the friendly threads for a few months, conserving my energy, but I have been on a few in the last couple of days and it's like a cesspit out there. It's sickening some of the stuff people are posting, yet they think it's reasonable. I'm not convinced those posters are anywhere near genuine.
Mumsnet have taken some stuff down, I think they should be removing more on the basis that if they aren't part of the solution then they are part of the problem.
