I think you misinterpreted sgc's comment to mean that everything about the industrial revolution was bad. More likely it meant that some things, not all, were bad. Of course sgc didn't specify what things—which made that comment pretty unsubstantive. Still, that's no reason to go on a flamewar tangent.

The site guidelines try to address this like so: "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
