Serious question, why is leaving a toaster plugged in a bad idea, but leaving the microwave, stove, refrigerator, televisions, clocks, fish tanks, washing machine, dryer, guitar amplifiers, computers, video game consoles, cellphone chargers, and lamps plugged in not a bad idea?
On one hand, you right boo. If you really want to go the extra paranoid mile, you should unplug everything to be safe. But that's a little too nuts. (Most) Toasters are still these near medieval devices that use fucking springs to keep the tray from falling and subsequently activating the coils that heat up to toast the bread. Most often, sure, those springs are probably fine; but after a while and having a toaster for a certain amount of time (and there's a lot of people out there that have toasters from when they were these fancy high tech devices and are 20+ years old, even if they're rich and fancy otherwise, it's weird), it isn't a stretch to say that those springs are probably wearing thin and all it takes is a slight depression of those springs to activate the heating coils (or any number of others situations that don't require
adults to activate it). Then all it takes is paper being close to it, a wooden cabinet overhead, toast being left in it, etc. and you've got yourself a much higher probability of a nice fire.
Most of the other things you mentioned require explicit negligence and/or a pretty big requirement of adult interaction for turning it on (although a dryer is another one that is a more-common-than-others fire hazard...actually I'd bet it's the most common out of anything discussed in here).
As for the other extremely important topic of toaster names...I'm with Chino on the first pic, it's a toaster oven. At least in the picture he posted, I've only seen those types called toaster ovens. Otherwise, it's just a 'toaster' in regards to the pop-up toaster. But a toaster
oven, mmm, now that is a different beast altogether, my dear watson.
I fucking love these discussions. DTF - Only discussion the real hard hitting, world-affecting topics.
