Religion would disappear within a few generations if children were
not brainwashed by it. Luckily for religion, children are programmed
to believe whatever adults tell them is true. Children can even take
nonsense threats about hellfire and eternal damnation as being
literally true, as well as miracles.
But for the survival of the mind-virus called religion, it is vital
that young people be infected. This can be by their parents or by
local infectors (priests, pastors, imams, rabbis, etc.) before they
develop a natural immunity to mind-viruses in the form of cognitive
ability and critical thinking.
Indeed the actions of the local infector is similar to that of
Typhoid Mary or any other person who has sought to infect many
people with a disease. The purpose of the infector, conscious or
not, is to spread the infection among those most vulnerable to it,
namely the very young and the old.
However in the process, the mental torment imposed on children can
fairly be called child abuse. The virus is injected into their brain
but the infectors seek to keep the child from resisting it, using
various kind of conditioning that can amount to torture.
