lol, what? That was a civil comment. This seems like an excellent example of the point being made. Replying to a perfectly reasonable but critical comment with "please be civil" is super condescending.
So is stuff like "one man's modus ponens".
Look, we get it, you're talking to people who found this stuff smart and interesting in the past. But we got tired of it. For me, I realized after awhile that the people I most admired in real life were pretty much the opposite of the people I was reading the most on the internet. None of the smartest people I know talk in this snooty online iamsosmart style.
