There's nothing wrong with asking questions, even if the answers aren't hard to find using other ways. Like I appreciate the question because it was something that had never even occurred to me, as obvious as it was in hindsight.

And even when the question is being asked in bad faith, discouraging people from asking questions can give them more credibility rather than less, because it looks like (soft) censorship, especially to anyone else who thinks it's a good question.
