I can’t take credit for this, as I read it elsewhere, but I think it is applicable here.
There have been a number of discussions lately trying to label people or companies (Gygax is sexist, WotC is evil, stupid, etc.). Rather than try to come to a conclusion, it can be better to simply describe actions.
Gary said sexist things. On multiple occasions. Over a period of many years. He also left really good impressions on may people who met or interacted with him at conventions or elsewhere. Others have had good and poor impressions from post he made on this board. There’s no need to “figure out” who he really was. Assuming the accounts are basically accurate, we are left with contradictions and complexity. Ultimately our actions are what others are left with. We cannot hope to understand what anyone is “really” thinking or feeling.
