Someone called? 
I work in stem, I've got the best of both /all worlds in my brain.
I can turn a car on a dime, and drive off road for pleasure in a 4x4.
I am excellent at special analysis.
I also can listen extremely well, and have trained as a counsellor to work in a women's charity (think women's aid or similar)
However, I agree there are differences to the sexes, in the main.
The male and female brains are different by and large.
We have equal rights and responsibilities under the law, and as citizens, but we are different.
To create a universe where a subject is excluded because of a pervasive trait such as gender, and where one is included, is not helpful.
Let me put that another way, generalising about gender, and attributed associated with that isn't helpful, as no doubt many of you know!
I like to have things explained to me sometimes and I listen intently, as it shows me the limit of that person's understanding. But as soon as I'm not learning anything, I turn away.
Many of you have discussed casual conversations in the pub as quite a sticking point, and I have also experienced this in pubs.
I have learned never to engage with the 'lads in the pub' as they are in the main boring, rude and dismissive of my knowledge and experience. I don't find their conversation on any subject interesting anyway, and don't feel the need to enlighten them on how stupid they are!
I don't 'throw my pearls to the swine', and prefer to keep my powder dry for important events amongst peers.
I try not to bore anyone when I'm talking with them, and keep an eye on them when speaking. There are as many ways as speaking as there are people, and it behoves us as experts to engage and not to patronise and assume incompetence as a default.
I understand I spent many years studying and doing postgrad degrees and I always assume others have the same experience until they prove otherwise by their own admission and /or talking shite
I think the thing to do is to interrupt men/women who over talk an expert, and simply say, "yes, thank you Jack, Jane made that point just now". Repeat ad infinitum until Jack gets the idea he need not interrupt, and to wind his neck in. Also to thank the expert for her contribution every time when the meeting is winding up.
We need to support each other to get the job done (men and women) and squish the overtalking person (whether a man or a woman)
We need to lean in for each other as well as ourselves (disclaimer, I thought that book LeanIn by Cheryl Sandburg was mostly awful and screamed white, educated, able bodied, supported, wealthy, privileged, indeed, after the death of her husband, she has said as much herself, never realising how difficult life could be for single mothers (duh))
I don't think mansplaining is a helpful term moving forward toward a more equatable and fair society- same as any stereotype it belittles and alienates.
I think overtalking is a better description of that unhelpful attribute where a non expert teaches the expert how to suck an egg.
I think the men who overtalking maybe have no radar for how boring they are, and have no idea about their privilege in any situation. Certainly having worked with men almost exclusively in my stem job, I think male interaction is very hierarchical and specialist.
I don't think men in general are trying to be personally insulting, but I do think they need to learn that from their privileged position they come across as boors quite a lot if they adopt a patronising over talking manner. I've seen men posturing and overtalking men in their quest to climb the greasy pole that is the male totem of power, or establish themselves as the expert in a side role (think of the character Brains in Thunderbirds)
My work with women is so much more relaxing by comparison where we get the job done in a more collaborative atmosphere.
