Is 1 crime more heinous than another just because it is motivated by "Hate"? I don't think so. Tell the family of a murder victim that their loss is not so bad because it was not motivated by hate. Evidence of hate can be useful as a motive, but should not be a crime in itself. Murder is murder period.
This is where you ignore the impact on society.
There are different degrees of murder. Do you want to get rid of all those and treat them all the same?
He said, murder is murder. Where hate crimes would be classified as 1st degree murder with aggravating factors. It would just be codifying those factors.
Murder is not just a single event of murder when it is a hate crime.
When one person kills one person over greed, jealousy, resentment, etc., there was a reason for it, and everyone else likely is safe since that reason does not apply to them.
But when it is a hare crime, then there is no reason for it, so it can't be avoided, and potentially tens of thousands of other people could also be at risk, through no fault of their own.
Normal murder does not threaten others, while hate crimes do.
