"not preprocessing itself [...] just someone writing things badly" I agree with that, but I think that is precisely the point of the quoted post: CSS preprocessors, not unlike compile-to-JS languages, try to make you write less, at the cost of pushing you to write badly. Of course, with a full mastery of LESS, you will not make those mistakes. But you will probably make them a lot while learning to become such a master.
