I'm not sure I understand your question, but there are lots of ways to speak the truth, and on HN you're expected to do so civilly and substantively. Personal attacks are especially not allowed.
Sometimes people justify their uncivil, unsubstantive comments by posing as warriors for the truth and so on, but this is silly, because the truth isn't served by such posturing at all, and rudeness makes a comment less persuasive.
