Sadly yes, b/c even the simplest things can go wrong quickly. E.g. people sometimes change light bulbs w/o turning off the power. Have you ever experienced a dead (or good, for that matter) bulb coming apart as you twist it out of the socket? Would you trust a naive person to properly handle that situation?
You are conflating naive and a barely functional human being.
If someone doesn't know what the electricity zaps and couldn't think two steps ahead then they definitely should be anywhere near a power circuits, operating a car or be allowed to vote.
EDIT: of course it should had been 'shouldn't be anywhere' but it's even better, so I leave it as is.
Can I now take it as confirmation from the two of you (justsomehnguy and micromacrofoot) that at least half of Americans who vote should not be allowed to vote?
If so, this may be the first time an important political question has been resolved without a light bulb turning on (figurative or otherwise).
That may be so, but what you say doesn't answer my question: can they unscrew a lightbulb that is literally falling apart as they unscrew it?
ANSWER:
If the power is off, they likely will remove the glass bulb (one piece), examine the situation and then unscrew the metal bulb base (second piece) and finally, remove any stray material in the (unpowered) socket.
If the power is on, the correct answer is "No, they likely cannot unscrew the bulb. Instead they will likely short the circuit, blow a breaker/fuse and put themselves in a situation where they must call in someone more knowledgeable, (or worse)."
With power off(easy case)?
With power on(difficult)?
