This comment exemplifies a pattern of rather useless comments that I've seen a lot of online recently, that are analogous to "contradiction - stating the opposing case with little or no evidence" on the argument pyramid: when a commentator X states a thing, commentator Y states that that thing isn't true, with no supporting evidence, but more importantly no additional value or elaboration added - just saying "that's wrong" without explaining why, or saying what is actually the case.
For instance, here, value would be added by stating what are the actual causes of suicide - or even adding research that supports your point even if you don't want to talk about what the actual causes are.
