verisimilitude you can check the true meaning of this word you used as your name ... if this is used as a name it means someone who refuse to accept the truth ...

this could be the reason for using the word "retard"
retard is an offensive word from any dictionary... I found the following meaning in one of them...
1. Used as a disparaging term of a mentally retarded person
2. A person that is considered to be foolish or socially inept

usually it goes back when someone says it to another but the QL MOD should pay attentions to this kind specially during this holy month ...
