Do you typically fly around on moonless nights below the surrounding terrain

Through valleys? No, not me. Others have. And yes, pilots in this
area (NW NJ) have slammed into the surrounding mountains on dark
nights. The terrain isn't far away from the airports. And sure,
those with GPS use it to help stay away from them. Don't you? Or
are you in the flatlands?

Interestingly, the second case in the following near-CFIT compilation
occurred in the NW NJ area... no, it wasn't GPS-related, but the point
is that it's not hard to hit terrain around here, even under ATC
control:

This whole scenario is a stretch. It's not gonna happen and even if it did,
I doubt that it would be much more than a temporary inconvenience.

Well, first you claimed GPS couldn't be spoofed, so you were wrong
there. Now you claim CFIT's couldn't happen if it was spoofed. I
politely disagree. Heck, even without GPS being screwed up, near
CFITs are damned common. In my neck of the woods, I think that
spoofing GPS could easily cause accidents.
