Person perpetually angry at something.
Gets drip fed bastardisations of news through facebook by Sharon, or DMG/GBeebies.
Picked paedos as a battle, because few defend paedos.
Spends her copious free time spotting paedos, identifiable by their checks notes happy meals, which are clearly for rechecks luring kids.
