Your examples are good. Clearly the racist versions of those crimes in your example are worse than the non-racist version. Certainly, if hate crimes legislation didn't exist, then I'd hope any judge would take that into account when sentencing. I guess part of it comes down to whether it's better to build this into law or just count it as part of the various things judges consider every time they sentence someone.
I'm not necessarily anti hate-crimes legislation - I'm just not 100% comfortable with it either. I certainly don't have a better solution.
