You only think that I'm making things personal because you think those questions, "what is philosophy?", "what is science?" are basic questions that it would be an embarrassment not to know the answers to.
In this case that might mean (a) providing enough information to explain why escalating the question is necessary to the discussion, as opposed to a closet insult, and (b) using impersonal language. For example, you already changed your wording from "do you know what science is" to "what is science". That's a big difference.
