Same with me and American accents, been told there exist more than Midwestern and Southern but blimey if I can tell a Chicago bloke from a Minnesota one.
I love almost all incarnations of English, though, so I wouldn't mind learning. ^_^
Why?
I assume you don't mean voice actors when you say that but what could possibly cause you to hate people for changing the way they speak?
That would mean no pirate accents! D:
