I don't want you to stop commenting! I'm just asking you to stick to HN's rules when you do.
Btw, there's a common bias that distorts basically everyone's judgment about this kind of thing (including mine, clearly): we underestimate our own harshness by, say, 10x, and overestimate the other's by another (say) 10x, and that compounds to a 100x distortion. I'd venture a guess that this is why your comment seemed to you like innocuous "pushing back", while it seemed to me like an obvious breaking of HN's rules. I don't know if that's helpful or not (probably not), but it's what came to mind.
