I get what you're saying but I think you can strike a better balance than just broadcasting to millions that Biden is a socialist and that that's a valid reason for not voting for him.
Isn't This American Life sort of "documentary" style reporting? In that case, the entire premise is to capture people as they are. They aren't broadcasting that Biden is a socialist and that that's a valid reason for not voting for him, they're broadcasting that this one person thinks that Biden is a socialist and that that's a valid reason for not voting for him. It might seem like semantics, but it's pretty crucial to this kind of reporting.
