I don't think he dismissed the original argument ("Facebook is bad for you") at all, he's just commenting on the use of bad rhetoric and how it detracts from Stallman's goal of convincing people not to use Facebook.

I don't think everyone would listen to a person flinging insult, even if their argument has some basis. I wouldn't listen to a person who rely on bad rhetoric either.
