Contrasting with some of the more sexual relationships of the other characters, Willow and Tara demonstrate a sentimental, soft, and consistent affection for each other. Some of this was pragmatic: the show was restricted in what it could present to viewers. Willow and Tara did not kiss until the fifth season in an episode that diverted the focus away from the display of affection when Buffy's mother dies in "The Body". Before this, much of their sexuality is represented by allusions to witchcraft; spells doubled for physical affection such as an erotic ritual in "Who Are You?" where Willow and Tara chant and perspire in a circle of light until Willow falls back on a pillow gasping and moaning. Within the Buffy universe, magic is portrayed in a mostly female realm. As opposed to it being evil, it is an earth-bound force that is most proficiently harvested by women. The treatment of the lesbian relationship as integral to magic, representative of each other (love is magic, magic is love), earned the series some critical commentary from conservative Christians. To avoid large-scale criticism, scenes had to be shot several different ways because censors would not allow some types of action on screen. In the fourth and fifth seasons, the characters could be shown on a bed, but not under the covers. Hannigan noted the inconsistent standards with the other relationships on the show: "you've got Spike and Harmony just going at it like rabbits, so it's very hypocritical". As a couple, Willow and Tara are treated by the rest of the Scoobies with acceptance and little fanfare. Susan Driver writes that younger viewers especially appreciate that Willow and Tara are able to be affectionate without becoming overly sexual, thus making them objects of fantasy for male enjoyment. Willow and Tara's influence on specifically younger female viewers is, according to Driver, "remarkable". Academics, however, comment that Willow is a less sexual character than the others in the show. She is displayed as "cuddly" in earlier seasons, often dressing in pink fuzzy sweaters resulting in an innocent tomboyishness. She becomes more feminine in her relationship with Tara, who is already feminine; no issues with gender are present in their union. Their relationship is sanitized and unthreatening to male viewers. When the series moved broadcast networks from The WB to UPN in 2001, some of the restrictions were relaxed. Willow and Tara are shown
