THERE'S NO JUSTIFICATION, IT'S SIMPLY WRONG!
Some people have mental retardation (intellectual disabilities). While mental retardation is not a bad word, when used to describe someone or something you think is bad or stupid it becomes another thoughtless hurtful word. People with intellectual disabilities are not bad. Their condition is not bad. The prejudice and discrimination to people with intellectual disabilities is BAD…and WRONG! Please stop using the word ‘retard’. It hurts individuals and families of those with disabilities.
