Projection

The amount of hate you have for a trait in yourself is proportional to the amount of hate you have for that same trait in other people.

h(x, y): |hate| in {x} for {y}
t(x, y): |trait|{x} in {y}
a(x): |amount| of {x}

T: any
Y: |you|
O: |other people|

A: a(h(Y, t(T, Y)))
B: a(h(Y, t(T, O)))

A ∝ B
