I get that Mumsnet is pretty left leaning it is basically the Guardian of the forum world. I guess this could be because women are more left leaning in general or it could represent the politics of the editorial team. Recent threads/posts around immigration, baby trapping and the NHS have been deleted with claims that the message breaks talk guidelines. I read many of the offending posts indeed I report many too however whenever I do report I make sure it complies with these guidelines (so I only report the last 2 and the first of the list below).
No personal attacks
No posts that break the law, including hate speech of any kind
No trolling, misleading or deliberately inflammatory behaviour
No trollhunting
No spamming
Often other posts which are deleted clearly aren't unless you very liberally interpret inflammatory behaviour, but then there are lots of left leaning inflammatory threads allowed to stand. Could further deletion messages reference the exact reason for their deletion? I suspect a lot gets deleted under item 2 despite this being obviously not breaking the law. Generally there is a right to free speech in the UK (although not on private forums) so very little you see on here actually breaks the law. Also how posts critical of men and women are treated differently is critism of some female decisions likely to be interpreted as trolling?
What I'm saying is I believe that even if I operate within the talk guidelines as referenced Posts/threads can still be deleted can they be extended to be more explicit about what posts are allowed?
