Speaking to The Daily Telegraph, he added: “This “debate” has been an example of “witch ethics” - a group of people know who the witch is and seek to burn her. It is one of the most dangerous human tendencies we have. It leads to lynching and genocide. Rather than argue and engage, there is a drive is to silence and, in the extreme, kill, based on their own moral certainty. That is not the sort of society we should live in.”
