Edit: (Context:
lib + imp = made up number * evil
con + imp = made up different number * evil)

Ah, an equation.

Fact 1: liberals are conservatives.
Fact 2: conservatives are liberals.
Fact 3: liberals are imperialists.

Now we can calculate the results:
evil = 0
liberal = 0
conservative = 0
imperialist = 0

Conclusion: liberal = evil, q.e.d.
