My comment was posted before mikeash described his comment that way, so unless you think we should be mind-readers, that's a hindsight fallacy. I never dreamt he was being sarcastic. In fact I still can't read his comment that way—to me it remains a striking expression of the right values of this site.

If I squint, I guess I can see that use of the word "civilized" as a bit aggressive, but really I think Mike was being hyperbolic for effect in his later description.
