No, that doesn't follow. What follows is that you should avoid low blows, so-called "tiny insults"*, and castigating "evil people" on HN—such perceptions are notoriously unreliable, and mostly result in reverse flames from people functioning the same way, just from the opposite point of view.
Instead, what you should do is respond to wrong information with correct information, neutrally and in a way that the rest of us can learn something from. Then you've contributed something good to the community. If you can't do that or don't want to, the other option is to simply not post.
Responding aggressively doesn't help—it only makes things worse. Nor is it in your interests, because to the extent that the audience is persuadable, aggressive comments like what you posted will sway them against your own position. If you happen to be right, that means that you've discredited the truth, which hurts everyone (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...).
* Everyone always underestimates the badness of their own infractions (e.g. "tiny") and overestimates the badness of others' (e.g. "evil"). If one weights each of those biases at 10x, that's a 100x distortion. No conversation can endure that sort of communication gap. https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...
