On the point about posters in FWR using obscure feminist terms that people don't know or understand: I find it ironic that people have used feminist terms, such as patriarchy, in other sections of Mumsnet, including e.g. Style and Beauty, and it hasn't seemed to be a turn-off for posters in those sections. But, when feminists use feminist terms in the feminist section, it's a problem?
I do, however, think that the language of feminism should as accessible as possible to as many women as possible, but my point is: FWR should not be held to a higher standard than the other Mumsnet boards.
Education of women about feminism or conversion of women to feminism does occur in FWR, but it's not the job or the duty of posters in the FWR section to educate or convince or convert other posters. If someone reading an FWR post does not understand a word, abbreviation, phrase or idea, then they are free to ask its meaning. Many posters do so and receive a short, easily understood explanation, given without judgement. It happens very frequently. Someone may be kind enough to give a newbie an answer, but I think nobody has a right to expect FWR to be their effort-free zone.
FWR posters come from a range of backgrounds. FWR posters are just ordinary Mumsnet members like you. It is a myth that they are all white, middle-class, feminist studies university academics sitting in their ivory towers as they allegedly "police" the feminism party-line. I only know of about 3 FWR regulars who are academics, and I think none of them "do feminism" as their job.
If you do decide to post on FWR, and you have been up all night with a sick child or had a long day at work followed by making dinner and putting the kids to bed, making you too tired to google a feminist term or get your head around a feminist idea, please try to bear in mind that perhaps FWR regulars may have had as stressful a day as you, or even more stressful. Regular posters on FWR are just ordinary women, who have busy lives too, just like you, with the same number of hours in their day. Like very many other voluntary unpaid activities, feminism is as much about what a women puts into it as what she takes from it.
