I always try to read the intent of the question. Some are clearly written to provoke and then all bets are off. But, if the question is genuine – even if ridiculous- I try to respect the “no such thing as a stupid question” rule. This is quite challenging to do when the Q is very easy to find an answer to online or through other readily available channels. If someone continually posts Q’s that really don’t require a collective effort to answer, and the asker is not taking onboard feedback, I may let diplomacy go out the window. But then, I’m open to feedback, so it’s a two-way street and fair.
