Anyone who uses social media to discuss their favourite tv shows or movies has probably run into a crazy fan or two. Most major franchises - Star Wars, Marvel, DC, Harry Potter, Doctor Who, Game of Thrones, Disney, etc- have a large following on social media that unfortunately includes some people whose goal is to make everyone else miserable. These "Toxic Fans" (or "Toxic Fandoms" as a group) are defined as fans that are overly negative towards opposing opinions, are possessive, entitled, and/or abusive towards people they think are "ruining their franchise". These groups of people have been in the spotlight recently for being so abusive they've made actors flee social media entirely. An example of this is with Rian Johnson's "Star Wars Episode VIII: The Last Jedi" (2017) and its character Rose Tico and actress Kelly Marie Tran.
Hating Brie Larson seems to be a full-time job for some people and they’re making a fair profit off toxic fandom. Typing her name into YouTube will generate results such as videos discussing her ‘Flat Bum’, ‘Avengers Cast Savagely Roast Brie Larson’, ‘Brie’s Bots Exposed’, and ‘Brie is ruining Marvel’ just to name a few. Despite both "Captain Marvel" and "Avengers Endgame" breaking box office history, the hate towards Brie Larson doesn’t seem to be evaporating.
