Oh, we should clearly just all agree to call our offspring George, Harry, Louis, Sam, or Ella, Grace, Lily and Mia.
I tend to wonder whether the people who come out with this kind of guff live in some kind of sealed monocultural dome - don't you ever get out and meet people from other places and cultures, who speak other languages, and have a completely different appreciation of what is 'normal' in naming terms? Who may not be primarily thinking of your comfort zone and ability to spell when naming their child?
Or that your Sam or Grace may go and live somewhere where those are really strange, unspellable names that provoke raised eyebrows and endless spelling requests?
