I'm not surprised: in the U.S., regional dialects or accents are often the subject of mockery or disdain.

This isn't specific to the US. In my (very small) home country, people who live in the capital perceive themselves as not having an accent, whereas all the other parts of the country have accents which sound provincial.

Everyone everywhere is looking for excuses to put other people down, I guess.
