And as a bonus when used against a man you will at the same time question his manliness. So actually I think this low blow argument might be even better used against men, but works against women. And for the specifics of the article. I see no explicit accusation of being emotional. "I was being hard on S" does not necessarily mean that the people being hard on another is emotional, since it could also mean almost the opposite: that you do not care about people's emotions. And this argument ("being too hard on") can be and is used on men. I do not see how this article relates to sexism, rather it relates to various low blow tactics in corporate politics.
