Is it just americans?
Every single time I watch TV, should it be something as innocuous as 'Housewives of New York', the people on the shows try to sound polite by using the word 'I' instead of 'ME' - especially the Countess who thinks she's so superior. Yet, why are they so stupid?
Is it only Americans who aren't taught the difference at school?
To put it very simply, it's 'I' if you are the subject of the sentence and 'ME' if it's being done to / with you, as the object of the sentence.
Is it normal that this grates on me so much, it's like fingernails down a blackboard?
