The term “hate speech” is frequently used in public discourse. I do not know if this is a legally defined concept, or if it is instituted by organizations like the Southern Poverty Law Center, for example.
Is there an impartial definition of hate speech which is meant to be evaluable based on certain attributes some speech act has, i.e. by a judge, as opposed to a sort of ad hoc list of forbidden speech acts that reflect the cultural norms and taboos of a society?
For example, while “hate speech” appears to be legal in the US (or, speech that does not directly incite people to acts of violence), it is illegal in Germany (Volkverhetzung) and Sweden.
Those laws appear to define hate speech in general terms, including a clause that basically states it is illegal to insult a particular social group:
…assaults the human dignity of others by insulting, maliciously maligning an aforementioned group, segments of the population or individuals because of their belonging to one of the aforementioned groups or segments of the population, or defaming segments of the population…
This strikes me as problematic. Assuming it is not actually upheld in daily life that it is illegal to “malign”, say, an ethnic or a religious group, it appears that if the law is actually attempted to be formulated in terms of general principles, it is not successfully enforced or implemented that way. For example, some debate has gone on regarding Quran burnings, which I read “was protected by Swedish laws about the freedom of expression”.
So: is “hate speech” an intrinsically definable and regulable legal concept, or is it de facto basically a dominant culture in society deciding somewhat democratically what values / opinions are considered wrong and to be made legally forbidden (i.e. Nazism)?
