Interactions

It is likely to intersect with facets such as:

Dehumanization: To portray someone as an inhuman monster is both dehumanization and demonization. These two facets are separate facets because you can also portray someone as "less than human, without being monstrous" or as "monstrous, but still fully human".
Othering: If he is so evil, he's certainly not one of us!
Categorist slurs: This category is bad that enough to be a bad word...
Justification through Kyriarchy: Bad traits gets constructed as associated with the underprivileged or oppressed category of people. Also, traits associated with the category gets constructed as bad. It goes both ways, and in both cases makes it harder for these people to succeed in society.
Politization of Category and Depolitization of Categorism: Positioning the demonization as normal while positioning disagreeing with it as "being political", thus creating a Biased Balance where people can position their favoring of the demonizers as "being neutral".

As well as with abstractions such as:

Categorization by emotional bias: When we see someone as a decent, it becomes hard to categorize this person as something we consider to be evil and vile.
Zero-category: Through demonizing a minority, it becomes easy to pretend that the majority category is not a category but instead simply regular good decent people.

Examples of applying this facet to a particular foci of categorism can include:

Sexism: Talking about one gender or another as being immoral, driven by selfishness and dark emotions.

Adam's homophobia: Part of Adam bullying Cedric by accusing him of being gay.
Mr Garrison's Homophobia: "Gay people, well, gay people are EVIL, evil right down to their cold black hearts..."
