Don't say that's retarded, it hurts special kids feelings NOT ABOUT CALLING SPECIAL KIDS RETARDED

Basically, they have been playing this BS video on the morning announcements for the past couple days. Basically, it's saying that because a word used to refer to a group and then became and insult and no one refers to them as that anymore, it's offensive to them.
"Well, it's just like gay people not wanting gay to be an insult"
Uh, no. Gay people still refer to themselves as gay. No one calls special kids retarded.
To be clear, it isn't about calling special kids retarded. It's about using retarded to insult normal people.
So yeah, discuss.
