That's one of those people that go around evangelizing over the fact that they are an atheist. They are every bit as annoying as a tub-thumping creationist. For famous examples see Dawkins or Pullman.
Most evangelical atheists you'll see on the internet are around 12 because when they grow up a bit they start to question why they are putting so much effort into something that, being atheists, they shouldn't really give that much of a shit about and go off and do something more enjoyable to them.
