Ah, I can relate to your stories. I worked in male-dominated industries, too many actually! The sheer ignorance is mind-boggling. You would almost think we live in a different century! I was a science and tech writer before coming to Steemit, and men are always so surprised......they can't quite believe that I know what IoT, neural networks, and the like are! I don't talk about this very much but it is important to vent occasionally. Science and technology is actually much easier to navigate than sexism and ignorance. That's my two cents.
