You see, some people are so small and have nothing more important going on in their lives, they engage in activities such as these. Nevermind that the author fails to grasp that guys is not necessarily of masculine gender, much like the pronoun "he" as in "he who...", or "man" as in "man is an animal that...". You may as well get worked up over the recent singular "they". I mean, I'm an individual, not a "we", so I take offense (grammatically, I do dislike singular they, but that's a grammatical quip not a seething ideological piece of nonsense).
