All crimes are motivated by hate. If something is motivated by kindness, can it by definition be a crime?
But that's the controversy: who decides if someone is motivated by love or by hate? Who's definition of love are we using?
Rather than try to wrestle with why people commit or don't commit crimes or how they feel homosexuality, Congress should let the courts follow in the same tradition they have since the founding of our country: punish people for crimes they have committed not thoughts that have crossed their minds. Prosecutors should provide evidence to as to whether someone committed a crime or not and leave the wastelands of inner motivations between the individual and God.
