In a community like HN there's also kind of a "meta-anecdote" that emerges. If there was a link, you'd expect to see at least someone posting an ancedote about how their friend got into violent games and then became violent themselves; instead it's mainly the opposite.

I'm still not arguing this observation is scientifically rigorous in any way whatsoever, merely that multiple ancedotes can be more useful than a single one. There could be other reasons such as those that are violent or hang out with those that are don't post on HN - but that also hints there is something more to it then just or even the violent games themselves.
