Hasn’t the hate crime law been used to silence and even prosecute grooming gang victims? I can’t remember details because it’s such a horrible situation that like many people I don’t like to pay attention to it.
But I think that alone is reason enough to abolish these laws. They can be weaponised by violent perpetrators in protected groups against victims who are not members of protected groups. And the most vulnerable victims are often not members of protected classes, so it’s making people unequal before the law.
I’d also point out that when hate crime laws were first introduced, the people who opposed them said it was “criminalising thoughts” and suggested it was a slippery slope. At that point nobody was suggesting “non-crime hate incidents” be recorded, so that seemed to many people like a silly thing to say. But the slippery slope argument was clearly correct. Is it possible to have hate crime laws on the books without sliding down the slippery slope? I don’t know the answer to that, but given what has already happened I find it unlikely that any positive outcomes from having these laws on the books outweigh the slippery slope risk.
