Debord has been a well known figure in far right circles for a while now
What is the intention of this comment? That Debord is “far right” or a reactionary? That people who read him are? That it’s interesting that a Marxist philosopher is read by reactionaries?
This happens a lot if you read books that aren't bestsellers. A thing that for decades you couldn't find a person who had heard of it suddenly is in television commercials and image macros because a character mentioned it in a movie, or some twitch streamer decided to rail about it for an hour, and it caught fire.
