Legalities
Hate speech is perceived to disparage a person or group of people based on their social or ethnic group, such as race, sex, age, ethnicity, nationality, religion, sexual orientation, gender identity, mental disorder, disability, language ability, ideology, social class, occupation, appearance (height, weight, skin color, etc.), mental capacity, and any other distinction that might be considered a liability. The term covers written as well as oral communication and some forms of behaviors in a public setting. It is also sometimes called antilocution and is the first point on Allport's scale which measures prejudice in a society. In many countries, deliberate use of hate speech is a criminal offence prohibited under incitement to hatred legislation. It is often alleged that the criminalization of hate speech is sometimes used to discourage legitimate discussion of negative aspects of voluntary behavior (such as political persuasion, religious adherence and philosophical allegiance). There is also some question as to whether or not hate speech falls under the protection of freedom of speech in some countries.
