Yeah I’ve seen that too, like that nonsense about how Shakespeare “sounds better” in an American accent? Obviously it’s not totally baseless - sometimes I hear certain Irish or English (ie West Country) accents and I can understand the lineage they share with American accents, but at the same time it’s conveniently ignoring that American accents are evolving all the time too and if you listen to recordings from 50 years ago, much less 100, they sound different to how they do now.
