Pronunciation Nazis PLEASE Get Over Yourselves
(1) Pronunciation is not a marker of intelligence or education level, but, rather, environment. In fact, most of us can identify a person's geographic origin by their pronunciation of certain words (like Canadians with the word "about").
(2) There are actually four correct pronunciations for the word Erudite, depending on the part of the world in which it is used. Since most of the key actors are not American, it makes the most sense to use the preferred English(UK) pronunciation, AIR-you-dyte.
(3) You should really take a hard look at the quality of your own life if you feel the need to harp on the pronunciation (or mispronunciation) of a word.
