But in recent history, it’s become what’s considered an ableist slur by many — a discriminating word in favor of able-bodied people.
“The word is considered hate speech because it offends people with intellectual and developmental disabilities, as well as the people that care for and support them,” Karleigh Jones, Special Olympics New Zealand athlete, said in a statement to Spread the Word to End The Word. “It alienates and excludes them.

Understandably, fans were upset and proceeded to let Kardashian know that they were offended by her language.
Thank you for that info.
