"So how do men stop mansplaining? That's a good question. How do you change behaviour when you don't know you're doing it and you don't understand what it is like to be on the receiving end?"
It seems only possible for women to influence men currently on a case by case basis using reason and focusing on truths to challenge the overarching patriarchal social structure which validates his male perspective.
My DH and I had a lot of intellectual wrestling at the beginning of our relationship, then he actually 'got' it. He only occasionally lapses. I've invested a lot into him in this way and I've said before that no woman can be expected to keep more than one man seeing this kind of sense in her life. It is massively time and energy consuming, frustrating and disheartening for her along the way. Women have lots more important and interesting things to be getting on with than teaching individual men not to mansplain.
I suppose it is about cultural change through raised awareness - which is a long term, resource-draining mission.
So in the meantime women should organise with only other women where possible and become adept at swiftly and mercilessly roasting any man who mansplains- so he learns to tread carefully in future.
What men can do, is be honest with themselves, to unflinchingly look at the misogyny they've absorbed, to admit the voice in their head that feels entitled, superior and impressive in relation to women. And to sometimes not speak and not share their opinion- to start with.
Maybe others have some tips too?
