All of you that say that they exept this word ("Narutard"), maybe you are trying to say that you do not care if somoene will know you're watching Naruto.
I don't mind if my friends will know that I watch it (They do know), BUT the meaning of the word is Naruto+Retard. It's base is insulting.
But maybe i you change the expression (Liek someone here said) it will be more appropriate.
