I'm not the OP, but as a child growing up in an anglophone country but with a 'low-prestige' accent (think Indian English or Singaporean English), it was ingrained to me pretty early on that the only 'proper' ways to speak were RP or General American, and one of the reasons was because all the kid shows I watched had characters who talked almost exclusively in those accents. 'Exotic' accents were used mostly for comedic value.

Having a greater variety of shows that model the diversity of the English language would probably have gone some way to dispelling that damaging self-belief? I really love the existence of shows like Derry Girls, because they make me less self-conscious of my 'exotic' accent.

That's a really interesting perspective that I hadn't considered, thank you for answering! I have what anyone would call a General American accent, so your experience isn't one I'd ever been personally exposed to growing up. I remember a lot of older sitcoms and cartoons using "exotic" accents for comedic value though, like you said, and it's obvious that can be damaging to anyone's self-esteem.
