ate speech – the advocacy of hatred based on nationality, race or religion – occupies an exceptional position in international law.
Generally speaking, the right to freedom of expression extends to unpopular ideas and statements which “shock, offend or disturb.” Nevertheless, a number of human rights treaties, including the ICCPR, not only permit states to prohibit hate speech but actually require them to do so.
In addition, one particular form of hate speech – incitement to genocide – is one of only a few types of acts recognised as a crime under international law, akin to war crimes and crimes against humanity.
