Sort of on the back of another thread, I've noticed recent deletions of the word 'moron' as disablist.
I''ve done some googling. It was used among a couple of other older terms, idiot and imbecile, by Henry H. Goddard, a psychologist at the turn of the 19th century to grade people of "low intelligence", and it was taken up to justify eugenics. So distasteful, yes.
Is it just that Goddard actually coined 'moron', and the other terms were pre-existing? Goddard himself disavowed it shortly afterwards, and it hasn't been in use medically for a very long time. I very much doubt that people who use the word are directly referring to learning disability- the word in that sense is long-obsolete. Much like the word 'cretin', which has a similar history.
Language changes, we all know that.
The issue gets more clear-cut, I think, when similarly-originated terms are used as insults separate to their initial meaning. It is NOT ok- regardless of the speaker's meaning and motivation- to, for example, use 'gay' to mean 'pathetic', because it is still primarily used to refer to people's sexual orientation, and making the word an insult is demeaning to them. Also words like 'retard', because alongside its general use, it is still used to abuse and insult people with learning disabilities.
That, in my opinion, should be the rule of thumb: if the initial meaning is long obsolete, fine; if it still gets used in a discriminatory sense about actually-existing groups of marginalised and oppressed people, not fine.
So after thinking about it, I don't think I agree that the word 'moron' should be deleted as disablist language.
So what do people think?
