That's an interesting opinion. I've never thought about it that way before. Now that I do, I find myself agreeing with you.
It's my opinion that murder is one of the few crimes that can be punished with extreme prejudice. By that I mean all you need to know is whether they did it or not and you're ready to punish them to the maximum extent of the law. (See: Be able to prove it in court) The actual harshness of the punishment should be dependent on what degree it is and nothing more.
At the same time, singling them out is giving preference where none is deserved. (As if to say, these guys deserve it less than those other guys. That's the subliminal message that is being sent, believe it or not.) Doing such undermines the goal you're trying to achieve because it's failing to properly teach kids that violence and whatnot in general is wrong.
When I think about it, I honestly don't think our schools have what it takes to realistically fight this problem. Perhaps we simply need to consider other ways to fight the problem that might be more successful?
It is not about who deserves more than the others by any means. Everyone falls into the categories I wrote in my comment. Everyone has an ethnic background, skin tone, sexual orientation, socioeconomic status, gender, ect. There is not preference given to anyone.
I think that there are few other buffers, other than education, that are between children and parents. When a parent teaches racism to a child; who is going to help that child learn tolerance so that they can function in society? Although parents have the right to raise their children, they do not have the right to teach behaviors in which inhibit a child's progress in society. Like this skinhead family, who is to stop them from teaching their child that it is wrong to kill another person simply b/c he is gay, with the acknowledgment that his motive has yet been determined in court. If he did so, with that motive, why not educate him about tolerance, and the repercussions of intolerance?
I honestly think that the victim could care less for a person's motivations. I mean, assuming you were still sentient in death, you'd be the same amount of upset if you knew it was because "you were black/gay/Jewish/Hispanic/Asian/Martian" or not, because your life was ruthlessly taken away from you.
So why should we care about motive? Murder is murder, after all, whether its a "hate crime" or not.
Well, one thing you have to keep in mind is intent. If I am driving and dose off, and then hit a girl riding her bike, then I have killed someone. My intentions were to drive to work, and not hurt anyone. Should I face the same penalty as other murder.
More pertinent to your comment. If I am at the bar with my spouse, and a drunk guy tries to make-out with my spouse and will not listen. I might take a swing at him; if it becomes a physical altercation, I might cause the other guy internal bleeding, and death. My intents that night were to have a good time, not get in a conflict. Then they transformed into, I want to get this obnoxious person away from my spouse. however, I end up killing him. Should I face the same sentence as a person who pre-arranged another's death? Someone who truly intended to kill someone.
I think that in this case, it was purposeful, and pre-arranged. That is speculation though.
