Let's say you are using an electric space heater to heat up your room and have some questions about the best place to keep it in your room.

You go to an HVAC forum and post the question. Instead of answering the question (or saying that it doesn't matter where you place it), people instead start lecturing you about how electric heating is very inefficient, and you should instead use a Heat Pump, then give you lots of details about heat pumps which are completely irrelevant to your specific issue.
