There's no way a comment like this can have good effects on HN. People sometimes think it's ok to post them if they come from that background themselves (not sure if this is true in your case, of course) but it still won't have a good effect. The combination of sweeping generalization with denunciatory language is bound to lead to a flamewar no matter how the chips fall.

Things that mitigate this effect are: rolling back the grand generalities, stating things neutrally, and (if relevant) talking about your personal experience and observations. I'm not sure those things would be enough to take a comment like this out of net-negative territory but they'd at least shorten its blast radius.
