A few years ago, there was a huge row about eugenics, abortion and disability. In 2015, the UK became the first country to vote to legalise mitochondrial donation — something which is often, unhelpfully, called “three-parent babies”. In reality, mitochondrial donation simply means taking the healthy mitochondria from another woman’s eggs, and using them to replace faulty ones which could otherwise have disastrous effects: it can cause everything from learning disabilities to early death.
There was backlash from religious groups, calling the move “eugenics”. But was it? The word “eugenics” can be used to refer to things like mitochondrial donation, insofar as it means something like “efforts to remove ‘harmful’ genes from the gene pool”. But the classic example of eugenics are things like the Nazi programme of forced sterilisation; a programme that did awful things to people against their will.
Using the term “eugenics” to refer to both was, I think, a semi-deliberate tactic. Opponents of mitochondrial donation were trying to associate those evil things in people’s minds with the more complex cases. That doesn’t mean that mitochondrial donation is automatically right. But the fact that a loose definition of the word “eugenics” can be used to apply to both it and Nazi murders does not make it necessarily wrong.
A similar sort of tactic appears to being deployed in the ongoing debate over the Government’s proposed legislation to ban conversion therapy.
It was not that many years ago that homosexuality was viewed as a mental illness requiring curing: the Diagnostic and Statistical Manual of Mental Disorders (DSM) listed same-sex attraction as a psychiatric disorder until 1973. And as I’ve written before, there’s not much evidence that you can change someone’s sexual orientation, while the methods used to do it have often been brutal: zapping people with electric shocks while showing them homoerotic images; chemical castration; even lobotomy, as recently as 1969.
“Conversion therapy” is, therefore, rightly held up as something unacceptable: the classic example of conversion therapy is a gay man or lesbian woman being forced, against his or her will, to submit to something approaching torture, in an almost certainly unsuccessful attempt to change his or her sexual orientation.
