Weird story time: My great grandfather was obviously the source of the autism in our family line. Man could not read social subtext to save his life. He felt driven to find some sort to group to belong to that had set meetings and such. For a 5 year span, he joined, like, everyone. Elks, masons, you name it. When we were helping him clean out his house in the early 90s we found a KKK uniform. We asked about it. Apparently it was billed as a men’s group and they just had costumes made. He went along with it for a few meeting and then the extracurriculars were discussed at his last meeting. He finally got the point of it. He got out. We had his calendar book from that year(and every year from the 30s-retirement) and we saw the date where he started crossing out the KKK meeting times.
Why he kept it? It was the best work his wife had ever done.
Several years later I asked my grandfather if his dad was racist. Basically, he said that his dad had gotten in trouble for not understanding the racist, unwritten policies he was supposed to enforce and kept asking why, as there was no logic to them.
