I'm not disputing the article. Discrimination happens. Humans are human. But let's not lose sight or minimize that women are (currently and historically) discriminated against on a scale that dwarfs this - in hiring, salary, and society at large.
Historically, completely agreed. Your other points of hiring, salary, and society at large I would not agree with outside of some edge cases that still need to be cleaned up.
Even historically speaking, that's a stretch. For a long period of human history, survival meant being able to plow fields, wrangle horses, chop down trees, hunt wooly mammoths, fight lions and all the other things that my ancestors would be ashamed of me for not being able to do. Men were expected to, and did, protect and provide for women because most men find those tasks easier than most women. Not even the hardest feminist would call that protection "discriminatory". It's only been relatively recently, on a grand scale, that most women could perform the tasks that needed to be performed to survive. More or less as soon as that happened, most of civilization became egalitarian almost overnight. There was some pushback in the 70's but as Bill Maher pointed out "we couldn't understand what you were rebelling against! Men in my father's day used to say 'I'll be damned if any wife of mine ever has to go to work!'"
