They don’t live in a vacuum but they are in their 70s and they might not follow this issue at all. They might watch liberal news. My parents even watch fox news but did not understand the BC issue at all.
Occams razor says it’s more likely that they are “out of it” than that they were paid off. Maybe someone could reach them now, being very gentle, and take them back to those sad days in 1961... Do they still have a copy of her BC?
To me that's pretty young still, as a NONE Natural Born, LOL!!!
