I’ve been noticing a trend among a lot of HN members where instead of contending with the arguments made in an article, they focus on the “off putting rhetoric” used by the author.

Make no mistake you are engaging in your own form of rhetoric when you respond like this. You are in effect moving the discussion away from the subject at hand, and towards the perceived faults in the author’s communication style. This is a rhetorical slight of hand and it’s highly disingenuous.

"Disingenuous?" Just because someone finds the style irksome, and chooses to share that here, they're deceptively, calculatingly trying to derail the conversation? That's an extremely cynical and uncharitable take.

If I were the author of the post, I'd value the feedback.
