So there.

Well, harrumph. Why don't you take your ball and go home, then.

I don't doubt you aren't alone in your opinion, sir. I just doubt that that opinion's terribly good for anything but getting those damn kids off your lawn.

Sorry, but this isn't suburbia anymore. It's no longer your lawn to play on. Just because a handful of Well Placed Citizens express an opinion does not make it the truth. You strike me as the sort of fellow who considers Richard Cohen a liberal columnist.

As for "argument from authority," it's a very telling title to your post. It occurs to me that what really offends you is that a) someone with authority, e.g. Rowling, might encourage the empowerment of the riffraff, and that b) said riffraff, e.g. yours truly, may dare to offer a substantive argument for our own empowerment.

The "argument from authority" or "appeal to authority" is one of the traditional fallacies in logic.

Should I explain "irony" next?

I suppose I walked into that one. Fair enough.
