Being politically correct is becoming more and more crucial these days. This tip will help not accidentally offend some people while you speak.
It’s called people first speech. A person is a person before anything else. They are not “Down syndrome people” or “autistic kids”. They are people with a disability. Putting the adjective before the noun labels the person as if they are less of a person. Obviously, that is not the intent, but as a supporter of correct English and everyone being happy, please be careful of what you say when you describe someone.
