Well the article claims that the original author behaves like a typical man. I love this: so we can fire sexist stereotypes at will, because if we see examples of men or women not fitting the stereotype, it is just a man acting like a woman or a woman acting like a man, so it doesn't count? Or in fact a woman acting like a jerk would be "acting like a man" and therefore reinforce the stereotype of men being jerks?
