NO prejudice from me. We are talking here about delivery, from presenters. One is technique and style, one is accent- that all from immigrant background had to work very hard at acquiring- yes, it is called 'received' pronunciation, and not for nothing. There is absolutely NOTHING prejudiced in my comment, but the reality.
Give me ONE, and hopefully THREE, examples, please.
No-one with a strong Asian (or even a hint) accent would get a presenter job, and there are none. This is NOT prejudice at all from me, an immigrant, married to an immigrant.
