The development of hate crimes is instructive. Like many things, it started with a sound - if subtle - concept. But it got dumbed down into something else.
The original conception of a hate crime, as I understood it, made sense: a crime (something that was already illegal) intended to inspire hatred or violence against the target(s). Think burning crosses in someone's yard, etc .... that kind of hate crime is along the lines of inciting a riot, and to me makes sense.
But people aren't very bright and tend to gloss over subtleties (and sadly, judges and lawyers are people). Soon enough, hate crime was understood to be any crime motivated by hatred for some protected minority. Basically just a way to punish bigots for being bigots. And that, to me, is wrong. It's essentially thought crime. If you murder someone, you should to jail. It shouldn't matter whether you killed them because they were black, because they followed a different religion, or because they had red hair.
And, there are some who even take it a step further, insisting that the expression of hatred alone should be a crime.
