Yes, frequently. It's not uncommon at all where I was raised (US South). We can talk to my father, or almost any member of his congregation, about how a national ID is a government plot to identify, control and harm the faithful.

It really isn't that uncommon of a belief.

really? still, to this day? one would think that evangelical Christians would skew conservative, and therefore be in favor of state/federal ID, for election security purposes.

These people are extremely conservative - well past treating "election security" as a primary concern and far closer to "welcoming the return of Jesus / the rapture" as their single motivating force.

Yes. The Bible Belt is very very real.

Yes. They (my parents) believed any sort of centralized federal ID was a "slippery slope," though they weren't educated enough to know and use that exact phrase, towards an implanted chip, barcode tattoo, or whatever form they were convinced it would take.

I certainly have. Multiple times.
