I like most of the male posters on here - have had a run in or two with a couple of them in areas I generally now steer clear of (mostly religion) but that's not because they are men, it's different opinions.
However, not long ago there was a male poster who specifically targeted relationships and who was generally quite aggressive to the OP - suggesting that it was her fault that her H/P was doing whatever it was he was doing, however bad that was. Sometimes he had valid points - but his crass heavyhandedness had many people up in arms over it. There is a time and a place for that, and mumsnet ain't it. People come here to AVOID being told that kind of shit.
I also find that the support here when you just want to rant, however irrational you are feeling, is usually good - someone will often come along and piss on your parade, but that's okay too (eventually) because it reminds you that you are just ranting.
Whereas in RL, I have friends who a) don't listen b) try and offer advice c) tell me to stop being daft. I don't need that when I want to rant! I want to rant! OKAY?
And while in general I do find that whole Men=Martians, Women=Venutians thing bizarre and slightly abhorrent, there are times when yes, I do find some of the male population are more about offering solutions and less about listening to the ranter and sympathising with her feelings.
I don't think we should change the name - but I do think it should be made clearer that all are welcome here: men, women, parents, grandparents, childcarers, parents-in-waiting and those who like a jolly good barney in the AIBU and Feminism topics.
