In 2018, the film "The Young Karl Marx" was released nationwide in Japan, mainly at Iwanami Hall in Tokyo. It was a joint work between Germany, France, and Belgium. Many of my Facebook friends are liberal, so it was naturally a hot topic. One day, someone's share appeared in my news feed. It was an article with a detailed review of the film. It said that Marx was by no means perfect, and that there were times when he rejected or quarreled with people who had different opinions from him. Although it is a depiction of a real person, it is a film, so it is unclear how much of the story is true. The article was deleted midway and disappeared. It is a strange phenomenon.
