This is a common misconception, idiote was often used interchangeably with citizen and should be understood as a citizen operating in his capacity as a citizen (and not say in a formal poltical or emissary function) but by no means one who wishes to disengage from the polis. As for Socrates, as he is at pains to emphasize in the Apology, he was no 'idiote'.
