On the issue of "collaborativeandlovely", i have to say that that is largely my experience among feminists and in feminist spaces. That's often when the best discussions happen: they run for longest, they thus include more people, less experienced people don't feel intimidated to come forward and ask questions, and respectful debate and discussion really teases out the issues in a very valuable way.
It's like MN generally, in a way, and the PARD concept. But part of what sparks change can also be conflict- and if MN remained a board full of "trust your own instincts, whatever feels right for you and your bubs, hun", then it would become stale, boring, and frankly useless.
Of course it's best if conflict in discussions could be approached respectfully, without shouting, without disingenuous digs etc., but we are human, and people sometimes get quite heated if they are passionate about something. And often, women's anger can really be a force for change, and is very justified: it's unhealthy to suppress that. I think it's fair enough to accept that sometimes anger will be part of the interactions we have as feminists, and it shouldn't be repressed as unfeminine and "not naice".
I think we can accept it as part of the tapestry of our experience, but it would be a shame if we didn't strive to build on humour, gentle enquiry and a willingness to listen and challenge respectfully. I think feminists can be really great at this, especially with each other. But this approach is often met with ridicule out there in the bad world, and devalued. I guarantee you that when a woman isn't being slapped down for being "shrill" or an "angry man-hater", she is being ignored as wishy-washy and unrealistic, not to be taken seriously.
For me, being a feminist now, and a feMNist here, means accepting the whole gamut of our humanity and really trying to hear each other so we can take things forward. That is why I get so angry about the man-trolls who try to silence us, wind us up, and channel our energies down a path which wastes our time and goodwill. And I (perhaps unfairly) get even more cross with the women who can't see what their game is, and chip in with "Actually, he's got a point there". What I would really like to see more of here on MN in 2012 is women supporting each other as feminists, and less of the dismissive attitude to feminism as something for ranting angryheads, because that truly is not an accurate or fair characterisation.
