I've always hated it. I think the "iz" sound is ugly, and it always makes me think of a dark middle-aged overweight woman who has a mustache.
Many years ago, when I was about 12 years old, my then brother-in-law began singing a dumb song that he was making up as he went along, a song that featured the name
Isabella and that seemed to be mocking it. I can't remember what prompted him to do it. He was distorting words slightly to rhyme with
Isabella. Part of it, for example:
My name is
Isabella La la la la, la la la la
My name is
IsabellaI run a little della (deli)
My name is
IsabellaDon't you think I'm swella?
Punctuated frequently with the "la la la" refrain.
Every time I see or hear the name, that "song" starts running through my head, so maybe my former brother-in-law prejudiced me against it early on lol.
