The point of the bit about Western Europe was to point out that hate crime laws in practice achieve the exact opposite of their intended goal: They make societies more bigoted. The US, which doesn't legislate against hate speech, has less hate crime than countries that do.
The point is to figure out what works, not "keep trying what we expected to work, but it didn't, but we've already sunken the cost of believing it, so we might as well keep trying."
