There's an ambiguity in the comment, but reading the comment charitably can dispel the notion that the person claimed any form of criticism is a form of maliciously bringing people down. Read it however you want, but taken in context I disagree that that's their intended claim. I think that poster meant that malicious criticism is something that can make unhappy people feel a little better about themselves.
