My maiden name is Clemence, pronounced klem-EHNSS, stress on the second syllable. All my life, people have been completely unable to deal with this name. They want it to be Clemens or Clements or Clement or Clemente, or pretty much anything except what it is. I can count on one hand the number of my friends, some of whom I've known for years, who are actually able to pronounce it correctly. And really, it is not difficult. I went to school with people named Przywojski and Stuggelmayer, and whose name did the teachers routinely mispronounce? You guessed it--mine. No matter how much I explained they just could.not.get.it.right. So based on my experience, I think Jewlz is right, and that people just can't deal with any prononciations they aren't familiar with. (Interestingly, when I lived in France, I had a different problem. Clemence is a French first name, and since my first name is spelled bizarrely and since the French way is to write LASTNAME Firstname, people tended to get my names the wrong way round and were very confused indeed when I attempted to explain.)
As far as the article goes, don't kill me guys (Jenn have mercy!) but I do actually see his point. Perhaps he could have expressed it in a less obnoxious manner, but I also find it depressing that British people are adopting American phrasing. One of my favourite things about the UK is how people talk and how different it is from the way I talk. Learning the different words and expressions is a point of pride for me, and one of the ways that I am learning to fit in here. Also, I am the official Word on American English among my colleagues (we teach English as a Foreign Language, so we often get questions from students about American English), which I quite enjoy. Ultimately, when I go to different countries, I want things to be properly DIFFERENT, not just a different version of America.
