Mumsnet is a very middle class bubble in itself as such it has hidden, codified and often virtue signalling and contradictory rules.
EG if you dare express a negative opinion on people playing/cheating the benefits system then posters will come down on you like a ton of bricks.
However, posters seem to think it's fun and acceptable to mock people who use the word 'hun' 'hunny' or 'babes' or who have ' "mummy' names or who post in a "NetMums" style (whatever that is) - weird huh?
Likewise tone is very important in relation to the style of responses.
EG A lot of posters here rail again gender stereotyping, but if you dare post that you're angry or in an angry tone you will be labelled aggressive etc.
Post the same dilemma saying you're upset - then you'll get a much more empathetic response.
There is a pattern that the few few responses set the tone for the rest.
This is the worst of Mumsnet
The best of Mumsnet will support you through problems and give very helpful advice and guidance.
AIBU (Am I Being Unreasonable) is a bearpit so expect challenging responses but they should prompt you to be self examining about what your issues are and not to just tear you down.
Chat and Relationships are known to be more gentle.
I know it may come across as gossip but it's really about finding the full story so people can help you - eg I don't think you're really upset about the pouches, but they symbolise much deeper issues, I was trying to get you to talk about those so I could offer you support and advice on the real problems you are going through.
Also people will advance search your user name to find out more about you - this is because Mumsnet is prone to 'trolls' who just post to stir things up or worse, get money, so it's about seeing if you are genuine.
