You said the pejorative statement was about those who do things differently. Saying "fuck this" makes it clear there's a strong objection to the idea(s) presented in the article, something "i disagree" just wouldn't convey in the slightest. Saying "fuck this morning person" would have been the statement your critique would fit.
