One could almost cite the furore that currently surrounds Facebook as proof of the existence of Original Sin. A social media network cosily described by its founder Mark Zuckerberg as a promoter of family ties and community feeling has a much darker side. One of the latest examples is the allegation that well-organised posts on Facebook played a crucial role in the whipping up of ill feeling against the Rohingya minority in Myanmar, which cost many lives and caused immense suffering. Last month in the Sri Lankan district of Kandy, anti-Muslim rioting was fomented by posts on social media networks to such an extent that the government intervened to prevent access to Facebook, WhatsApp and several other platforms.
