Nationalism doesn’t need the apolitical “NS” fandom to succeed. To the extent that people become wrapped up in this subculture, they tend to disengage from politics and encourage others to do so. If people actually tried to do what the historic NSDAP did which was contest state power and win offices all over Germany on behalf of their own ideology, the “NS” fandom would oppose this because that would require engaging with the system and a sense of political realism.
