Why do people always say "this is not reddit"? I never even heard of reddit till I saw those comments. And I think this observation made over and over again usually adds less to the discussion than the politically incorrect statements this comment is made in response to.

Also, I don't think your link relates the the comment. Your link is about choosing between gzip and deflate; the comment you found objectionable was about the irony of gzipping a file that is in a format that also support deflate (so you might compress a compressed file; which I think can actually make the file larger).
