I remember reading (relatively recently) research showing conservatives literally believe badvthingscdo not happen to good people. If they know someone personally who they know is good, and something bad happens to them, they either think it is a rare example of bad luck and they will help out, or they will decide that person must not have been a good person.
It allows them to justify the mental gymnastics of being anti-abortion but paying for their daughter's "procedure" at the same time. A "good" family member who gets cancer deserves help, but why should they fund cancer care for those morally bankrupt <fill in the "other"> people?
Apparently they have overactive amygdalas, among other issues, and a reduced ability to engage critical thinking towards their own beliefs.
So, yes, they kind of are cult members. But they can't be easily deprogrammed, and even if we purged this lot, we would still end up with some cropping up again.
Could be linked to extended living under a corrupt conservative government, too. Constantly being told to ignore evidence, a sense of learned helplessness, and rising corporate authoritarianism could lead to psychotic symptoms. It would also lead to an increased desure to escape the stresses reality through cannabis.
On a less facetious note, did diagnostic criteria change?
