I don't know. I'm just very uneasy with the idea of 'hate crime' as such - when there are clear indications of racial/gender motivations during an actual assault (e.g. language used), then I think that should be prosecuted as a hate crime.
But if that isn't the case, and the hatred of women/ethnic minorities is only found after the crime, through searching their belongings/internet history, then to me that's verging into the realm of thought crime. There's no actual way of knowing if they were thinking that during the crime.
Also, does the fact that someone was thinking 'I hate women' when they murdered a woman make it worse than if they were a male feminist who murdered a woman?
Personally, I don't think so - I think the crime is equally bad no matter what motivated it.
