Have you ever heard of this term? I found this video yesterday and I started to search information about this:
I also found this website: https://accentism.org/
"The Accentism Project is run by Dr Erin Carrie and Dr Rob Drummond, who are both sociolinguists at Manchester Metropolitan University with a shared interest in language variation and change, language attitudes and perceptions, and the prejudice and discrimination shown towards regional and social language varieties and their speakers – in particular, regional dialects, youth language, and foreign accents."
If you have a story you can submit it! Here are some of the stories:

Have you ever being judged because of your accent? I have!
