Captain America was a comic book character created specifically to fight fascism, which is perhaps why the son of the man who created the Marvel superhero is so frustrated with seeing Cap associated with Donald Trump.

Jack Kirby and Joe Simon’s Captain America has been the focal point of the Marvel Cinematic Universe and battling otherworldly threats in recent years, but the character has a long history of battling against fascist threats to America and championing freedom and democracy. Which is probably why Neal Kirby, the son of Jack, is so upset about images that featured Trump associated with Captain America as part of the riot that staged a failed coup attempt in Washington last week.
