Laws against incitement to racial or religious hatred violate the fundamental principles under which laws against incitement are just.
Hating people based on race or religion or whatever category you want is not illegal. Whether it is right or not is completely irrelevant. It is not illegal to feel or think a certain way, and it should never be illegal to feel or think a certain way. Even, for example, fancying children is not illegal--it is only in actions that it becomes illegal. This is as it should be.
The law of incitement properly covers inciting someone to commit a crime. You can incite to murder, you can incite to theft. Racial hatred is not a crime, so incitement to racial hatred, that is, incitement something which is not a crime, should not be a crime.
