Actual Point: The reason I am hesitant about following the advice of this article is that it encourages you to divide the world into jerks and nice people. It's very easy to be a jerk to a jerk. If you are a jerk to a jerk, suddenly everyone on the project has to deal with two jerks.
I do agree that there are behaviors that just shouldn't be accepted, and there are lots of examples of them online. But you (2) do need to be mindful of your response to those behaviors. Make sure your response isn't to engage in those behaviors yourself.
(1 & 2) and by you, I mostly mean me. I am totally writing to myself here.
