Help on street car named desire?

Stanley sees Blanche objectively for what she is, beyond the mask of her pretense and her manners. She is a fallen woman pretending to be virtuous, a pretending to be a virgin. He finds her self-deception to be intolerable, because her "illusions" place her "above" him in terms of cl and manners. However, what he cannot appreciate is that Blanche's "illusions" are a kind of coping mechanism by which she maintains her fragile sanity. Stanley, has a brutish conception of truth, because his sense of the truth lacks compion. Blanche cannot accept the truth, and so she creates a world of illusions, hoping that this world of illusions will protect and console her. Stanley will not permit her this conceit-- and as a result, he destroys her.
