I know this is a topic we've discussed multiple times here, but I didn't want to necro an old thread, and a thought just occurred to me concerning it, which is...
We generally consider it a bit psycho when performers like Madonna, Phylicia Rashad, Dorit Kemsley, etc. put on an an obviously mannered/phony accent in an attempt to seem more posh or elegant than they believe they would using their "natural" accents. So why don't we judge people who work to lose their working class/regional accents (a heavy Queens, Southern, or Baltimore accent, for instance) in a similar attempt to be taken more seriously or sound more "intelligent"? In fact, we sometimes even judge actors who don't ever make an attempt to mask their ethnic or regional accents. I for one worked hard to correct my Brooklyn-bred accent as an adult (which will still occasionally surface when I'm drunk or with my family for a long time), and no one would accuse me of "delusion" or "narcissism" for it. I know plenty of people who've done the same with their natural Southern (US) accents.
So why the double standard? Both involve training yourself to speak unnaturally (respective to your origins) in order to fool others into receiving you differently than they might have before. Why is one considered an "affect" but not the other?
