Furthermore, trying to outrun stigma through linguistic gymnastics often produces short-lived results. Consider what linguists call the "euphemism treadmill." Over time, lexical euphemisms have a tendency to take on the stigma of the words they replace, so new euphemisms are coined to take their place (www.cmaj.ca/lookup/doi/10.1503/cmaj.109-3308).
Thus "lame" becomes "crippled," which becomes "handicapped," which becomes "disabled," which becomes "differently abled," and so on. Person-first language is a structural euphemism. It is possible, then, that "person with autism" will one day be deemed offensive — as some now consider "autistic person" — and demands will arise for a new grammatical twist.

We do not typically say a "person who is beautiful," for instance, or a "person who is intelligent."

Remember when blind people were called "visually challenged"?
That didn't stick around too long.
