What am I reaching for exactly?
If you are reading racist posts and letting them go, then are you not part of the problem?
If you are reading and not engaging with anything then are you not part of the problem?
The whole reason this section is gamed, by men who pose as women to make women look bad, and to screenshot their posts, and deleted posts to post on other forums to make women look bad, is because they want to shut the whole of mumsnet down.
People who stand by watching and then pointing fingers at those who engage are just as bad as the people who wait til someone falls and then go in and kick them, and kick them hard.
Perhaps instead of having a go at other people for what they say, just say things yourself? Engage, don't engage, whatever. But don't think that every post on here is posted by a woman, or indeed a feminist. More men on here than in a working man's club in the late 70s.
