These kind of questions are a good indicator about the documentation quality of a project. They are valuable input that can help you to put your project presentation on a much higher level.
Also from "inside" a project it is very easy to forget about the most obvious question a person might have looking at it for the first time - these questions are the best signal for exactly that happening.
There is no reason to interpret any kind of question in a hostile way - it only shows that you must be living in a personal environment of too-much-aggression. Take a break.
We are living in an age of upcoming aggression and ongoing regression of human brain capabilities (too much poison everywhere) - we have to stay aware of that and actively try to overcome these emotional aberration (and, of course, constantly work on the causes) - it is not easy, but if we all try it, we can all win.
