It's wrong to use offensive terms.
Dave is at a work training session on sensitivity and is shown a video fo some people who struggle with mental disabilities.
Dave wants to react to the video.
Dave tells the group that the people in the video must have a hard time in life.
"Dave tells the group that the ""retards"" in the video must have a hard time in life."
The group agrees with Dave and are happy that he recognizes that people with mental disabilities face a bigger struggle.
The group is disgusted that Dave would use that derogatory term and are made uncomfortable.
