“While hate speech on social media is a problem affecting the world, not many countries resort to such extreme measures as are in the offing in Nigeria. Ignoring strong criticism, the nation's highest lawmaking body, the Senate, is preparing a law which will make it possible to sentence to death by hanging anybody convicted of spreading hate speech. The Prohibition of Hate Speech Bill is being sponsored by Senator Aliyu Sabi Abdullahi, a lawmaker of the ruling All Progressives Congress party. The bill, which was initially thrown out following a barrage of attacks, resurfaced suddenly a fortnight ago, going through two readings in just two weeks. It is a very extensive piece of legislation, which covers a slew of possible wrongdoings, including the publication or presentation of material deemed to stir up ethnic hatred. It also takes aim at written or visual acts seen as threatening, abusive, insulting or offensive.
