I think the point about believing women when something is sexist is a fair one. I mean it's self evident sometimes wrong ends of sticks might be grasped.
But if I can illustrate, before I engaged with feminism I had an argument with a friend of mine who was complaining about a whole spectrum of sexist behaviour at work.
I quite simply didn't want to believe it, and I was very dismissive of her. Although it was part of a chain of events that caused me to look into feminism, I don't particularly want to repeat my behaviour.
Point is I didn't take her seriously and listen properly. I did apologise, but when it comes to future interactions my aim is that if and when something gets raised any women feels taken seriously and listened to. I think that's the salient point there.
It's also worth pointing out, just if you play the odds if another hypothetical situation comes up what are the chances of systemic sexism and misogyny vs a genuine wrong end of the stick? I think our own answers to that question very much lay plainly how important feminism is or isn't to us personally.
Someone asked me up thread what my disagreement/not understanding of feminism entails. In the first instance I think feminism gets such a hammering in public debates I don't particularly want to add my voice to that cacophony, especially as I'm not sure I would actually be right, and the devil has enough advocates already. In terms of not understanding, my own lack of knowledge and insight is my responsibility that I can resolve on my own time.
Essentially as part of the listening and taking women seriously thing goes feminism gets a free pass in my mind until monumentally important things like violence towards women, gendered pay gaps and general inequality is tackled.
I'm working on writing fiction and I have found feminist analysis as far as I get it so far incredibly useful as a tool for improving characterising women which in turn stands to make better actual stories all round.
