No it isn't. You - fundamentally - don't get to control what people say to you. You need to filter how to take that. And that's incredibly hard. Especially in open source. You need to both be able to ignore (some version of "idiots, who can't be bothered to read") and be openminded enough to take weird requests, because they could be the starting point of a new major contributor. The second is optional, as long as you are happy just doing your thing, but then the former probably won't become a problem for you.
