Scalzi snarks people, story at 11
So Scalzi makes a post about receiving a boring email from "one of those nutbag childfree folks". Gretchen shows up and takes exception to his description of childfree people. To which Scalzi responds by basically telling her to shut the hell up. There is some back and forth between the two of them, before the thread turns to a discussion of childfree lifestyle between other commenters.

That is, until electric_bonzai jumps in, presumably linked from cf_hardcore. Several commenters respond to tell them how wrong, wrong and utterly wrong cf people are.

Scalzi makes a second post, snarking both Gretchen and, especially, the person who commented on cf_hardcore with a "lesson" for him. The snark is, as always, delicious:

spitzandeyeball: 1. Internets 101: When you publish something on a public blog and neglect to disable the comment function, you have already given readers your permission to reply. This little slice of Internet magic is also known as the First Amendment.

Scalzi: Reading this person’s understanding of how the First Amendment applies in these instances is like being slathered in a thick coat of ignorant, and then being put out into the sun to dry out before a second coat is applied, which itself will be topped off by a sealant of complete and utter stupid, and lightly drizzled with a glistening varnish of epic fail.

More comments from people baffled at the thought of a childfree comm. Baffled, I tell you.

Back at the first post, Scalzi and Gretchen make up, though that doesn't stop people from continuing to share their thoughts over multiple comments.
