I'm not talking about rights, I'm talking about manners. Everyone has the right to communicate any way they want, but I also have the right to call them out on that. If you have a public, open-source project on GitHub, and you regularly accept and respond to issues/pull-requests/suggestions, you are obviously presenting yourself to the world. It is basic courtesy to not be hostile in such communication.
