Stalls certainly do cause crashes.

Sometimes, but usually not, at least if the pilot is competent. If they were
that dangerous, pilots would die during training, while practicing them.

BTW, when the engine 'stalls', we call it an engine failure, to avoid confusion.

Passengers may not use the same terminology.

When the passenger says "the engine stalled," it's highly unlikely that he or
she is referring to an aerodynamic stall, which does not involve the engine.

If the passenger had any flight experience, which is likely for any GA
passenger, they too would have used the correct term (engine failure).

That is irrelevant. Even a passenger can recognize an engine st--failure, and
an engine failure is a lot more dangerous than a stall in the vast majority of
cases.
