I agree with your remark about loving your enemy as far as actions are concerned. But for me the cognitive basis is the trust in an unrestricted causality. 'I cannot hate him, because he must do what he does.' That means for me more Spinoza than the prophets.
Nothing in oratory is more important than to win for the orator the favour of his hearer, and to have the latter so affected as to be swayed by something resembling an impulse of the spirit impetu quodam animi or emotion perturbatione, rather than by judgment or deliberation. For men decide far more problems by hate, or love, or lust, or rage, or sorrow, or joy, or hope, or fear, or illusion, or some other inward emotion aliqua permotione mentis, than by reality or authority, or any legal standard, or judicial precedent or statute.
Number one, it is absolutely critical that we tone down the rhetoric when it comes to the immigration debate, because there has been an undertone that has been ugly. Oftentimes, it has been directed at the Hispanic community. We have seen hate crimes skyrocket in the wake of the immigration debate as it has been conducted in Washington, and that is unacceptable.
