If that's how you really feel, then it's good that you posted it. Like Emerson says, speak your words like cannonballs. Obviously it's a saying that I live by. . .
But, I'm afraid to say that you are absolutely wrong. Linguists have debunked the mentality that you expressed time and time again. What you are doing here is "othering" the chancellor of UCD. It's not because she speaks poor English that you have a problem with her; it's because she does not speak the same kind of English as yourself.
I taught many international students as a college instructor (up to four or five international students per class of twenty). The majority of them had a better written command of English than most of my native students, however it was more difficult to understand them when they spoke simply because American English was not their mother tongue. In some cases, like the case of East Indians, they learn British English (which explains their strong written command of it). This complicates the situation when they come to America because their pronunciation is trying to follow a different pronunciation to begin with. However, according to the British, we Americans make no sense when we talk as well. If you went to England, would you be offended if someone told you to "SPEAK ENGLISH BETTER!"?
I'd be willing to bet this woman can read, write, and comprehend English at a much higher level than 99.99% of the American population, probably even more than yourself, but because she has an accent, there will always be people who mistake that for inferiority. It's unfortunate, it's prejudiced, and it's just plain wrong.
