Don't say Tolkien would never allow people to expand on his work, and then when proven wrong shift the goalpost to "He would never allow people to expand his work in ways that upset terminally online man-babies." Those aren't the same point.
He SPECIFICALLY states in that quote that people would expand on the parts of hiss tories he only "sketched", which is in direct opposition to what you are saying. The truth is that you know fuck all about Tolkien and you know fuck all about what he envisioned for his work.
