Now imagine being a clever, white 18-year old, not at all racist and not at all privileged either, away from home for the first time, in a lecture or class in (say) sociology, or politics, or philosophy, where a lecturer asserts, perhaps quite aggressively, that white people are inherently racist. Your own experience screams that this is wrong. But do you challenge it? Of course not – after all, it may have, and could certainly be presented as having, the effect of “marginalising minority groups”; and your own institution has told you, through formal training and via its website, that this is racism and we must all stand up to it.

So you keep quiet. So does everyone else; and the lie spreads. Repeat for white privilege, or immigration, or religion; perhaps also, given similar training and encouragement, for abortion, or the trans debate, or… Repeat for a thousand students a day, every day, for the whole term.

There is in Shia Islam the most useful concept of Ketman. It is the practice of concealing or denying your true beliefs in the face of religious persecution. At best our hypothetical student spends her university career – possibly, the way things are going, the rest of her life – practising a secular form of Ketman. Or worse: habitual self-censorship of her outer voice suffocates the inner one too; she starts to believe what she is parroting; she denounces others as racists, or transphobes or whatever; and then after three or four years, starts working for a publisher, or a media outlet, or a big corporation; and the euthanasia of the West continues.
