Litwank!
Patrick and Teresa Nielsen Hayden, editors, have a blog, which is often interesting and usually wank-free. They do get occasional trolls, which are dealt with by having their comments "disemvowelled", e.g. "mg y sck".

In an entry entitled "Story for beginners", Patrick writes about a book reviewer who doesn't seem to get that sometimes a zombie is just a zombie, and an author who doesn't get why he doesn't get it.

People comment and all is fine until a poster called Cija takes umbrage:

It's really great that admitting in print that you don't quite get something but like it anyway inspires such a terrific sense of superiority in everyone who does get it, and by great I actually mean problematic and off-putting.

And continues in this vein for several ensuing comments, until:

Patrick: Over here on Earth-1, I was pretty sure this discussion hadn't actually been primarily about whether Michael Knight's review was nice enough to Kelly Link or not.

Cija: I didn't have any difficulty understanding that you (and Westerfeld) knew it was a positive review; I just thought that you characterized its tone, and the reviewer's powers of understanding, unfairly, most particularly in the assumption that we can tell from that review that its writer isn't a sf reader or doesn't get the fantastic.

Patrick: Not to put too fine a point on it, fuck you. On what basis do you accuse me of any such characterization?

Cija protests that she wasn't complaining about him, Patrick continues snitty, and Teresa steps in to request that everyone take a chill pill. Several comments later, Patrick apologizes to Cija, and everything simmers down, until Yonmei decides to chip in her two cents:

So, for future reference, given that Patrick's comment has not been disemvowelled: "Not to put too fine a point on it, fuck you" is now to be considered a polite response?

And they're off again.
