But you know, we're people too, and we have human opinions. This was an exchange between two linguists:
It seems that we need to distinguish between disliking an accent and thinking that it's wrong or worse than the standard. We know that all dialects (and indeed languages) are equally valid, equally correct and equally suitable for use. This is where we differ from many non-linguists, who often think that a person speaks in a non-standard way because they're lazy or stupid. We also know that objectively, accents don't sound stupid or unfriendly or untrustworthy: those are values projected onto speakers of that dialect by the listener. We're like non-linguists, though, in thinking that some accents are simply not as suited to our own preference. And we also know how much people judge you based solely on the way you speak - more reason than any other to moderate your accent if you think people might regard it unfavourably.
