The biggest problem with hate crime laws is that they are aimed at protecting certain groups, and are not applied where hate really exists.
My problem with hate crimes is that it criminalizes
thought, not
action. How can you prove, beyond a reasonable doubt, what someone was thinking? Just like OZ said, most crimes, and especially violent crimes, are hateful. You engage in them based upon your hate, whether it is hate of society, hate of financial situation, etc.
