Position, stand, attitude denote a more or less fixed mental point of view or way of regarding something.
Position and stand both imply reference to a question at issue or to a matter about which there is difference of opinion.
Position, however, is often the milder term, since it, unlike stand, seldom connotes aggressiveness or defiance of a widely held or popular opinion.
Attitude suggests a personal or, sometimes, a group or communal point of view, especially one that is colored by personal or party feeling, is influenced by one’s environment or the fashion of the moment, and is, on the whole, more the product of temperament or of emotion than of thought or conviction.
