Note: This article has been updated since publication in May’s Village magazine. The Irish courts recently awarded €75,000 damages for a defamatory comment published on Facebook. Digital Rights Ireland described this judgment as a “wake-up call for a lot of people” that the law of the land also applies online. When did we reach this tipping point? When did some people start to feel entitled to casually publish defamatory smears that have no basis in reality? I strongly support freedom of expression about ideas, including the right to blaspheme and robustly to criticise and ridicule harmful ideas. I also support reasonable limits to freedom of expression in order to protect people as opposed to ideas, including laws against defamation and incitement to violence and to other crimes. From an ethical perspective, I encourage civil discourse over online rage and hate. We live in a topsy turvy ethical world where people casually spread ridiculous personal smears, including that LGBT campaigner Peter Tatchell is homophobic, feminist Germaine Greer is misogynistic, comedian Ricky Gervais is transphobic, and Richard Dawkins is whatever defamatory smear emerges from the roll of your dice. Gerry Adams was unjustly labelled a racist because of a tweet that he wrote about a movie. While I and others have strongly criticised Gerry Adams for his involvement with the IRA, we should not allow this to justify unrelated personal smears about him. We should defend the rights of those with whom we disagree as well as those with whom we agree. I have been called racist for saying that two thirds of Catholics live in the global south, fascist for opposing thugs assaulting people on the streets of Dublin, and the political silencing word of ‘Islamophobic’ for saying that anti-Muslim bigotry is bad and criticism of Islam is good. Atheist Ireland has been targeted with disgusting smears that cross lines even by today’s online standards, which have finally caused us to realise that some people online simply cannot be reasoned with. These smears are not only unjust to the people being smeared, and subject to the laws of defamation, but they also dilute the power of important words, and leave us with no useful words to describe actual incidents of hatred and bigotry against vulnerable people. They are the modern warning of the boy who called wolf. They often depend on using words in an ideological way, in order to try to force people to accept their biased assumptions before even starting the discussion. At a recent Rationalist International Conference in Tallinn, Estonia, sexual rights activist and philosopher Tommi Paalanen of Finland argued that we should define words in ways that are coherent, universal and inclusive, with clear and justified boundaries, and free from ideological assumptions that tilt the discussion. For example, ‘conversion therapy’ for gay people is not therapy and does not convert. ‘Safe spaces’ assume other spaces are not safe. ‘Cultural appropriation’ as an idea leads to ethnic purity not free cultural exchange. Calling ‘micro-aggressions’ a violent act diminishes the concept of violence. Saying that ‘you cannot question our experiences’ or you must ‘check your privilege’ serve to silence discussion. The worst smears typically come from people on the authoritarian left of the political spectrum. They know how everybody else should think and behave, and it is not enough to agree with most of what they say. Any disagreement justifies personal abuse and defamation. If you are only 99% along their ideological pathway, they will dial the personal abuse up to eleven about the 1% on which you might differ. They also do not understand satire, and will typically respond to this statement by arguing about the one-percent figure, you fuckhead. There are at least four ways that these smears can spread. The first way is where an individual, like American shock-blogger PZ Myers, spends years spreading hatred of people. For example, when Richard Dawkins wrote in his memoir that he was sexually abused as a child with little long-term effects, Myers outrageously wrote that Dawkins “seems to have developed a callous indifference to the sexual abuse of children”. Thankfully Myers’ blog network imploded last year when some of its bloggers finally turned on each other, like a mix between ‘Reservoir Dogs’ and ‘the Little Shop of Horrors’. A second way is when unco-ordinated Internet mobs unjustly attack an individual, like British scientist Tim Hunt, and the defamation spreads spontaneously online, and then into mainstream media. This is an extension of the idea that it takes religion to cause good people to do bad things. Hunt gave an impromptu short speech at the World Conference of Science Journalists in Seoul, in which he said that scientists should work in gender-segregated labs, because the trouble with “girls” is that they cause men to fall in love with them and cry. He was publicly smeared as a misogynist and had to resign from his position as an honorary professor with the University College London’s Faculty of Life Sciences, and from the Royal Society’s Biological Sciences Awards Committee. These smears were spread online mostly by decent people who believed the original story, and who believed that they were doing good by exposing somebody who they believed was bad, or at least who had engaged in bad behaviour. The mainstream media, who should have had more responsible editorial checks and balances, spread the smears uncritically. But the people spreading the smears were mistaken. Painstaking research by English author and politician, Louise Mensch, later revealed that Hunt, and other audience members, were smiling; that Hunt ended his toast with congratulations to women in science, and a wish that nothing would hold them back; that Hunt was mocking himself, using an ironic tone to do so; and that he had sat down to laughter and applause. A third way is in university campuses, where students unions or college authorities ‘de-platform’ or ‘disinvite’ people from speaking engagements. The supposed reason is to prevent these people from spreading beliefs that the censors believe to be harmful,
