Have you ever seen a Hollywood movie where the police chief was not an ill-tempered black man? You probably have, but not recently. Have you ever seen a Hollywood movie where the vegan didn't prepare and serve inedible food and wasn't a fussy and fanatical hypocrite? You probably haven't, ever.
The stock character has been with us long before movies were made in Hollywood. Vegans, meanwhile, are a relatively recent addition to the scene. How did they get such an overwhelmingly bad reputation so thoroughly so quickly? They are fussy, it must be conceded, but I think the key to the question lies in their example making others confront habits and thoughts they'd prefer were left unquestioned. That is never a pleasant thing. Does the target audience of these films find some pleasure in putting these vegans in their place? A guilty conscience is quite capable of shooting a messenger. Especially a fussy messenger.
Vegans I've met have been thoughtful people and their food is tasty and nutritious. Their depiction in the world of film is false and undeserved. I suspect the Hollywood image is the result of laziness and willingness to pander to a complacent audience. Maybe even cave in to pressure from a wealthy and politically active meat industry. My advice? Speak out against these negative characterizations and don't let these stereotypes take root.
