There was an overwhelming 'scientific' consensus about the role of witches in changing the weather too. It is, and remains, a fundamentally religious based belief.
Though poor breeding and the lack of natural selection, as there is no longer any infant mortality of note in the western world, probably plays a part here.too. Genetic mutations build up remarkably quickly over a few generations until you have entire classes of society hysterically shrieking that mutant rights are human rights.
Just look at your St Greta... Either very poor genetics, fetal alcohol syndrome, or most likely both. Rather than pojnting to abusive parents however the cucks and weirdos pronounce her a prophet and take every word from a 12 year old as the gospel.
Mutant people believe mutant things and it is likely a fatal flaw in democracy that their views have to taken seriously.
Back when the science really was settled, and sacrificing a virgin to the gods would see a bountiful harvest next year
There's not many virgins about now so they'd have to burn Greta or Bugsy
