Why would this only affect minorities in the first place? Anti-racism laws don't need a list of ethnicities they protect do they? They simply have to state that discrimination on the grounds of race is intolerable.
So why would hate crime laws be any different? If the law is written with a specific list of protected minorities then it's a badly written law. But that doesn't mean that the concept of a hate crime law is any way flawed.
The claim of a list of minorities is a long argued strawman. And that's all it is.
The Matthew Shepard Act quite clearly defines "hate crime" as a violent act causing death or bodily injury because of the actual or perceived race, color, religion, national origin, sexual orientation, gender, gender identity or disability of the victim.
No list of minorities. No discrimination against white people. None of the utter bollocks we've seen in this thread arguing against hate crimes in fact.
