Good point, I never considered that. Still they are adults , and seem to be able to find every kind of conspiracy theory out there that will support their cause, or defame anyone with differing views than themselves.

I suspect there may be some of each possibility. Home schooling has been around long enough for there to be large chunks f adults who are genuinely ignorant of history, never having been exposed to it.

I think you are right with your possibility #2 . It seems impossible to not be aware of these facts at some level. The power of fundamentalism and what it can do to the human mind is truly frightening. The capacity to
“Seek ” becomes totally eradicated. If you cannot acknowledge the horrors of the past committed by your Theology , you are a danger, not only to others, but your very own humanity. That’s the point I am trying to make with them, all Theologies have/can kill people by intent and passively. When desiring to promote and apply them today, they should always be viewed through the lens of history or in the case of Christianity, two lenses, the lens of history and the lens of what Jesus taught.
