I think he confused you with another member who I’ve had the same issue with in the past (shitting on other people’s work in a non-constructive way - not going to name them here). Not sure why he thinks that’s you, since you express support and enthusiasm for other people’s work frequently.
Or he read some of your posts about the sequel trilogy/post-Disney Star Wars material and is conflating that negativity with your opinions of fan projects. Not sure.
