mental retards are not disabled!
They mentally still function. Their cognition is impaired in various ways to various degrees.
Visually disabled people are blind. Visually impaired people use glasses or can't drive, etc.
Retards; for short, literally are mentally retarded by something; which literally using the meaning of the words could be temporary. The amount of drugs you take can retard your mental function...
Fuck all you ignorant PC morons! Wish you could grow up... but a moron is unable to get past the level of a teenager, generally speaking. So I'm wasting my time; I'm not a psychologist or special education teacher and even so you may be permanently moronic. The whole medical term was created because people were too PC about the prior medical terms: idiot, imbecile and moron. A century later and history repeats but we're still dancing around on a new replacement term.
