Funny. When I worked at the Alumni office at a university, a former graduate called and expressed his anger because
we had, Fred, listed as his first name when in reality, it was, Frederick. I apologized and told him I would correct it right away.
Believe me, it took everything I had not to put in, Fredo ... but I didn't.
If a person doesn't like that or any other name other than the one he wants one should comply. Fredo, in and of itself just doesn't
refer to Italians - and some people don't like that - but also to an idiot as in, The Godfather.
Btw ... If I was Michael I would have done the same thing.
