I also remember one thread that really boiled my piss where a woman got so angry at her partner because Nutella on their bed clothes that she threw objects at him and slammed a door so hard it broke the plaster on the walls. Obviously in mumsnet land it was the partners fault and he must have done something to trigger it. Anyone who pointed out that domestic violence can happen to anyone male or female was roundly piled on.
And I bet they all told her she was perfectly reasonable for reacting that way, but if the roles were reversed and it was then man who had done it, it would be "999 NOW", "LTB" etc etc.
What used to really annoy me when I was on the site was a woman posting about being in an abusive relationship, but with no money, no friends or family and literally no where to go, being rounded on and told "But WHY are you with him, do you not care about your children? Leave NOW, there has to be SOMEWHERE you can go. Pack a bag and go TONIGHT" when there may have literally been absolutely nowhere the poor woman could go.
I know because it happened to a friend of mine, though thankfully for her I doubt she posted on Mumsnet looking for advice at the time because replies like that would have broken her.
