Is the Fandom for Heated Rivalry, Taylor Swift, Ariana Grande and Others Too Intense? Psychological Analysis

It's one thing to enjoy something and to be a fan, but it's another thing if it reaches a level of extreme intensity. In my new video, I respond to a viewer question on my YouTube channel, Dr. Seth: Psychologist, about "toxic fandom."

What is your opinion on the subject? When do you think that fandom crosses a line into something that's psychologically unhealthy? If you have a thought, feel free to leave a comment for the video!
