1. Superiority - "I have the truth and they don't."
2. Separation - I no longer spend time with them. They are seen as "impure."
3. Caricature - Because I don't know them, I caricature them. They now become one dimensional.
4. Passive & Active Oppression - Now these become the type of people I can push away and ignore. Passively at first, then over time, actively.
