Hate speech Should be defined as.... "Speech intended to motivate violence and or discrimination against a group or individuals of a group for nothing more than their being a member of said group or the defining characteristics or practices either physical, religious, cultural or genetic that identify that group." Under this definition terms like White Privilege would and should be hate speech.
Hate speech should not be banned it should be challenged, loudly and openly. Debated exposed and defeated. What hate speech is in practice is thought and speech control by those that can not defend their own biases without the power to silence their detractors!
Hate speech? I despise that term. Speech can be hateful. Angry, hateful is not something that should be allowed. Sunlight is the best disinfectant
