Kaliber: "I'm offended! He called be the b-word!" Skip: "Dumb?" My friends are retarded
Oh gosh I am surprised at what you are saying. Why are you talking about disabled people?
Some people in this world are retards. I don't mean to hurt your feelings, but that's life and you should live with it.
While it is true that there are a lot of people with special needs in this world, by putting them down you're going to be making a lot of people think that you're cruel. They will say that there's no reason for you to use such hurtful language when speaking about those who have special needs.
