That’s an unfortunate abuse for sure. Like many truths, there are evil people who will misuse it to their own gain, but that misuse of truth doesn’t make it any less true.
IMO, were it an absolute truth, far fewer could take advantage. As it stands, it's the belief or unknown that allows them to reap from the gullible.
To the OP, I feel the term is often denominational. I was raised in a southern baptist church and rarely heard a sermon that "born again" wasn't used.
