Having spent most of my working life in a predominantly, frequently entirely, male environment, bar me. I really cannot see the problem. Women where no women have been before are excellent at making those with fixed views unfix them and at asking the 'Emperor's New Clothes' questions.
Anyway I found after a few meetings where I showed that I could hold my own against my male peers, they soon 'forgot' I was female and just treated me as a member of the group.
I have never held with this 'acting like one of the boys' nonsense. I was myself and it was surprising how fast the engineers I worked with got used to it.
