it really is not in any way accurate to say that there are "two crimes" involved in a hate crime.
Starting with what you said, here's what I would say:
Opponents of hate crime laws claim that the laws are a slippery slope towards criminalizing thought and that hate, no matter how egregious, should not be subject to legislation.
What these people do not understand, however, is that hate crimes are not like the crime they might look like on the surface.
When someone vandalizes a group's property
because of who the group is, and specifically because the group is a vulnerable minority, the crime is not merely vandalism, it is indeed vandalism with intent to terrorize, or at least intimidate.
Hmm, here's an example. Breaking into a dwelling with the intent to catch a nap is not the same crime as breaking into a building with the intent to commit a serious crime. The law does recognize the difference, and does punish the second more severely than the first -- even though both offenders may have done exactly the same thing.
Here's another one, also from the Criminal Code of Canada:
403. Every one who fraudulently personates any person, living or dead,
(a) with intent to gain advantage for himself or another person,
(b) with intent to obtain any property or an interest in any property, or
(c) with intent to cause disadvantage to the person whom he personates or another person,
is guilty of ...
-- in that case, the act itself isn't a crime unless it is done with a particular intent.
212. (1) Every one who
... (i) applies or administers to a person or causes that person to take any drug, intoxicating liquor, matter or thing with intent to stupefy or overpower that person in order thereby to enable any person to have illicit sexual intercourse with that person, ...
is guilty of ...
and then there's
245. Every one who administers or causes to be administered to any person or causes any person to take poison or any other destructive or noxious thing is guilty of an indictable offence and liable
(a) to imprisonment for a term not exceeding fourteen years, if he intends thereby to endanger the life of or to cause bodily harm to that person; or
(b) to imprisonment for a term not exceeding two years, if he intends thereby to aggrieve or annoy that person.
No analogy is perfect, but I think these are more more like pears than oranges, if we're talking apples.
However, hate crimes legislation is seldom framed that way -- with express reference to the dual nature of the intent (the intent, not the crime -- although also the effects, if the intent is achieved).
Usually they refer to motivation, which is framed as "hate". That is, I would say, somewhat unsophisticated. And it commonly applies as a sentencing consideration. Again, my Criminal Code says:
718.2 A court that imposes a sentence shall also take into consideration the following principles:
(a) a sentence should be increased or reduced to account for any relevant aggravating or mitigating circumstances relating to the offence or the offender, and, without limiting the generality of the foregoing,
(i) evidence that the offence was motivated by bias, prejudice or hate based on race, national or ethnic origin, language, colour, religion, sex, age, mental or physical disability, sexual orientation, or any other similar factor,
(ii) evidence that the offender, in committing the offence, abused the offender’s spouse or common-law partner,
(ii.1) evidence that the offender, in committing the offence, abused a person under the age of eighteen years,
(iii) evidence that the offender, in committing the offence, abused a position of trust or authority in relation to the victim,
(iv) evidence that the offence was committed for the benefit of, at the direction of or in association with a criminal organization, or
(v) evidence that the offence was a terrorism offence
shall be deemed to be aggravating circumstances; ...
Yikes. I did not realize that we had included sex in the list. Hurray us!
I just find it hard to think of an act as being "motivated by" hate. I see it as being motivated by a desire to exert power, control the behaviour of all members of the group, and like that. But then, I suppose that many people who do such things are hardly articulate or self-aware enough to know that's why they're doing them; they just hate those _______.
Anyhow. One offence, same intent -- to cause whatever harm is to be caused to the direct victim -- but a different motivation for causing the harm.
And one reason for addressing the motivation is that it distinguishes the act committed by the fact that it is not impulsive. It is calculated. And that is something that may make it more amenable to general deterrence: to the
threat of severe punishment actually operating to prevent people from committing the crimes.
We do, after all, generally regard homicide for profit as somewhat more heinous than homicide committed in a drunken fit of rage, and reflect that opprobrium in our sentencing -- but also partly because people committing homicide for profit may be more likely to think twice than drunks in fits of rage.
