"Typical stereo electronics will (probably) not kill you if somehow a short develops to ground."
It is not short to ground but short to case, that we worry about and we (probably) don't want to be killed.
"The real exception is tubed electronics, and Color tube TVs. Both carry fatal voltages inside, and should be treated with respect.
Any 110V device carry fatal voltage inside and should be treated with respect.
"And no one does not have to be worried about items with only a two prong plug."
You have to be worried if equipment was designed to be used with three prong plug. Two prong plug devices are designed differently (plastic case or metal case separated by plastic inside). Converting device designed to work with ground prong (isolation class I) using cheater plugs is unwise and dangerous. Recommending it to others is even worse.
