The OP has already given us context that makes your contrived example unlikely: they want to turn off just the main light, and in a specific bedroom. My extrapolation was reasonable, yours is a reach.
There's no reason to hunt for a poor parallel to shut down discussion.
I'm not sure what is being discussed? OP is a bad parent for wanting to turn off exactly one light in his child's bedroom? If so, yes, there is plenty of reason to shut down this discussion.
