Look at all the victims in horror fiction, they are typically representatives of the kinds of people who the dominant culture of the time disapproved of, now, look at the survivors, they typically represent the kinds of people that the dominant culture of the time most valued. The work of horror is a ritual, you see, the slasher is a scapegoat, he acts as an executioner of the people who the elites of society wish to be rid of, thus putting away the evils from their midst without blood being upon the hands of those who wished for those they hated to be purged. Then the killer usually gets taken out by the precious pet of the elites, showing that the thing that represents their most cherished values has the power to vanquish an evil that the corrupt would fall to, kind of like how it was only those who rejected Elohim/Jehovah/Yahweh whose firstborn children had died in Ancient Egypt, those who worshipped him had their firstborn children be protected from the curse of death, showing how greater the one God was over the various Gods of the Egyptian pantheon. It's a cleansing ritual where the elite's concept of sin is purged by a scapegoat, who is then themselves purged by the representative of the elite's concept of virtue, which acts as an affirmation of the superiority of the elite's preferred cultural values. This is how the black gangbanger went from being a typical stock victim, to being replaced by the white jock psychopathic bully who epitomizes both the aryan ideal and the "chad" archetype, the promoted cultural values had shifted, and thus the ones which are sought to be removed from society had changed along with them. Same goes for the one who survives, no longer the innocent shy white virgin, but now it's unusually either some persecuted "minority", or an outspoken "ally" for said "minorities".
