the manner in which one displays a lack of knowledge and general retardedness, often considered politcally incorrect due to the fact that the word's root comes from a mental disorder

A person born with a mental condition and therefore has to work a million times harder to be able to do simple things (such as learn and communicate) that we take for granted. On top of this, a retard will usually suffer a lot of ridicule from society because people fear what they do not understand. The people who choose to make fun of the mental retarded tend to be complete morons and cannot comprehend that these people have feelings and emotions just like anyone else.
I find it amusing that saying somebody has cancer would not be taken as a joke and yet, using another disease such as mental retarded as an insult is common among society, and many do not realize that it is very offensive and that there is something seriously wrong about it.
