Kevin Smith explains that he doesn't deliberately make his movies offensive to upset nuns or Catholics. Instead, he views what makes a movie "dirty" from a Catholic perspective as how it influences a person's feelings about sex, shame, and disgust. If a film provokes those feelings, it is not considered dirty, but rather a Catholic movie that aligns with certain moral perspectives.
He emphasizes that his own films are intentionally rooted in Catholic values or themes, challenging the typical notion of dirtiness. Smith's approach is to create movies that evoke a sense of discomfort or shame about the body or sexuality, which he views as consistent with Catholic morality rather than mere vulgarity or scandal.
