Earlier quoted context omitted.
Yes well. Looking at that list there seems to be something of a consensus on the -afi. Also just because 112 different spellings have been used, doesn't mean all 112 spellings are correct. Anyway it's a fun idea and I'm just nit picking.
Define correctness in this context.
If I had to say, I guess correct would be the closest phonetic spelling to the Arabic, and as I understand that would be Gaddafi (in Libya) or Qaddafi (more generally). Or you could use what he has used himself in the past, which I have just discovered is: Gadhafi [0].
So without even nailing your colours to the mast over the correct definition of 'correct' in this context perhaps you might agree that Gadaffi is probably incorrect for any sensible definition of 'correct' in this context.
Or perhaps we could all agree to just call him 'that evil motherfucker from Libya'.
