Hate speech is public expressions which spread, incite, promote or justify hatred, discrimination or hostility towards a specific group. They contribute to a general climate of intolerance which in turn makes attacks more probable against those given groups.

The Criminal Code defines the criminal offense of incitement to violence and hatred in the art. 325:

1. Whoever, through the press, radio, television, computer system or network, at a public meeting or otherwise publicly incites or publicly makes available leaflets, pictures or other material that call for violence or hatred directed against a group of persons or a member of a group because of their racial, religious, national or ethnic affiliation, origin, color, sex, sexual orientation, gender identity, disability or any other characteristics, shall be punished by imprisonment of up to three years.
