Most authors of published work fall over themselves to provide links or sources to their material.
I suspect you are either not proud of your published work, or providing a link or examples would diminish rather than strengthen your position in this debate. It's easy to argue about morals and social contracts if you've published a literary work; less so if, for example, it winds up being a fan DnD extension module on DriveThruRPG.
Someone is querying your credentials to learn about you, where you're coming from, what perspective you have, what skin you have, so to speak, in the game. Dodging behind some notion of having to "earn" your credentials when you have taken a very strong and contrarian position is disingenuous.
