I don't think there's any difference in the way people face sexism in the software engineering field. I expect it's much the same sexism that people experienced in law and medicine; I'm not sure why there would be any material difference. The field is dominated by one gender and they do their best to prevent entrance by the other gender. It's played out this same way, as you point out, so many times in the past.
On the contrary, I'd ask you what makes software engineering so special that it wouldn't fall into this historic pitfall.
Re-read what I wrote. To clarify further: I was talking about engineering in general, not software engineering in particular. Women entered the fields of law, medicine, and engineering all at the same time in the 60s and 70s. They faced sexism in all three. They have since come to be extremely well represented in law and medicine and even dominate some sub-fields, such as pediatrics and obstetrics/gynecology. At the same time, women's representation in engineering has barely budged from 3% to 13% since 1970. [0]
Looking at the facts, it seems clear that engineers are far more sexist than doctors or lawyers. Where other professionals have decided that they don't need to pretend superiority over an entire gender, engineers have chosen to embrace last century's discarded psuedo-science. Sad.
