Richard Dawkins, leading biologist and atheist crusader, has a self-described "passion for truth".
But as his Twitter timeline documents in excruciating detail, he often gets confused between the definitions of 'truth' and "obsessive and unnecessary dedication to accuracy,": this week his renewed attack on 'clock boy' Ahmed Mohamed has proved once again that Dawkins doesn't know when to step away from the internet.
Keen Muslim amateur inventor brings a homemade clock project to school to show his science teacher. The boy gets interrogated by five police officer, arrested and taken to the station accused of making and bringing a bomb to school.
Cue: international outrage at the racial profiling and an outpouring of support for Ahmed and his career ambitions.
Ahmed's parents, who have since relocated the family to Qatar, are now suing the school board for $15m in damages and demanding an apology for their son's arrest in September.
Now, the story according to Richard Dawkins:
Teenage Muslim 'hoax boy' definitely brings a fake bomb to school rather than a clock. Possibly wanted to get arrested.
Teenager, rather than his parents, then decides to take legal action over the matter.
Teenager's status as a child is questioned.
Dawkins points out that a 10-year-old in Syria was forced to behead a regime soldier by Isis fighters. (We think the logic is 'young people can do bad stuff.')
Brilliant scientist continues to quibble over how good/bad Ahmed's clock was.
Champion of truth and logic says his comparison between Ahmed and a boy made to do terrible things by Isis wasn't a comparison, then adds James Bulger's killers into the mix.
Dawkins's Twitter feed continues to alternate between messages defending his analogy, and retweeting praise of his books.
