Hate speech as a crime is an oxymoron in a society that values freedom of expression sufficiently to enshrine it in the Bill of Rights.
But there are plenty of morons out there who support the idea.
Hate crimes rest on the rather dubiously assumption that it is somehow more wrong to commit first degree murder against my neighbor because he belongs to an ethnicity that I dislike than it is to kill him because he kicked my dog.
Intent, with relation to criminal guilt, is primarily useful to establishing the difference between willful acts and acts committed through culpable negligence, or to be offered in extenuation or exculpation. Other than that, your intent cannot make you any more or any less guilty of a crime.
If you had trouble with that paragraph, you probably think hate crimes are a good idea.
