In a class presentation, Cartman
argues that "gingers" - people with red hair,
freckles,
and pale skin - are creepy and evil. He explains they suffer from
"gingervitis" and that their light skin comes from their lack of a
soul. He also
argues that they cannot stand the sun, and that Kyle, who has auburn hair - but not
light skin and freckles - is a "daywalker."
His speech encourages other students to discriminate against
gingers, and Kyle decides to make his own presentation about the
genetic causes of ginger traits. Kyle interviews a family with
ginger children, and it soon becomes apparent that although
Cartman's prejudiced ideas about gingers are untrue, the fact
remains that the general public, even their own parents, carry a
similar bigoted hatred and intolerance toward them. Kyle's status
as a "daywalker" prevents anybody from listening, though, so he,
Stan,
and Kenny agree that Cartman needs to be
taught a lesson. They get together in the night to dye Cartman's
hair red, bleach his skin a lighter hue, and give him henna freckles, to
make him "ginger," after which, Cartman begins to be discriminated
against by the kids he influenced by his speech. However, Cartman
becomes a leader of the "Ginger Separatist Movement," initially
demanding to be treated like everyone else.
Cartman's movement quickly becomes violent and Hitler-esque in tone. He begins to
preach that gingers are, in fact, the "chosen race" and orders the
eradication of all non-gingers from the earth. Following Cartman's
orders, the gingers abduct as many of South Park's children as they
can, including Stan and Kyle, then bring them to their meeting
place, the Sunset Room at the Airport Hilton, to throw them all
into a pit of lava.
Kyle is chosen as the first to die, but before the gingers throw
him into the lava, he whispers to Cartman that he has merely been
modified to look ginger, and Cartman is shocked. He then tells his
followers that he has suddenly had an epiphany and now realizes
that everybody has to get along. As the other children are freed,
Kyle mutters to Cartman that he is a manipulative asshole. Cartman
(for once) agrees, but doesn't care as long as he isn't killed by
the people of his movement.
