What is a controversial question? To some Christians, its a question they don't have an answer to. In that case, "
I don't know" might be a good answer
. Jesus answered some pretty controversial questions, so imo, if you know the answer, answer the question. Jesus even answered a lot of "
gotcha questions" when the Pharisees accused him of breaking the law, so I don't think we should back down from controversy or run from questions we dislike. No such thing as a dumb question, only dumb answers. Of course, if someone is just mocking you, then perhaps their questions should be ignored. JMO
