Stephanie is a perfect example of a conservative suffering cognitive dissonance - she's desperately trying to "rationalize" (like the article explains) but can't seem to form any logical explanation for her obvious personality disorder; she lacks empathy for others. Therefore she tries to change the subject entirely (muslims? racism? wtf?), she tries to point her fingers at others instead (attempting to shift the focus from herself) and utterly fails at making any sense whatsoever.
psy·cho·path
n.
A person with an antisocial personality disorder, manifested in amoral behavior without empathy or remorse
They lack empathy for their fellow human beings. Sounds like a strong word, but it is the truth.
