Well I do know that it was big in Catholic parochial schools (which I attended for 10 years in the 50s and 60s))that I even heard mentioned of its current existence when I was a kid. The nuns would attempt to correct the ‘mistake’ or possibly ‘demonic interference’. As I don’t have any lefties in my family or friends so I don’t know of the extent.
Not the bible per se. But definitely a catholic school thing

True. See my post 78.
“Not the Bible per se. But definitely a catholic school thing.”
There’s a BIG difference between Catholic traditions and
what the Bible teaches.
BIG difference. - as in the difference between
salvation by God
and
salvation by self.
