I'm not sure I've even met a person I believe would be deeply disturbed by aliens being confirmed as real.

Most find it interesting, exciting, or vaguely potentially alarming - in the same way an unknown rustle in the jungle might be alarming until you know it isn't dangerous. But not "deeply psychologically disturbing".

The only people I think could be genuinely deeply disturbed by the prospect of alien life may be deeply religious folks, surely not a representatively high percentage of HN visits.

My guess is a text-only message board with zero identity verification contains a higher percent brigading and sockpuppet content in general.
