That is not true at all.
Such a statement is only a testament of your ignorance to the character.
We understand that Nolan will not be using Robin and we are fine with it. It's posts like this that get the debates going. Robin is a serious character that has the potential to be portrayed terrifically on screen
under the right direction.
Well I guess you'd need a little brightening up after Bob Kane's and Bill Finger's original comics. Batman was originally conceived as a killer who toted a gun. There is even an infamous Kane/Finger panel in which Batman is flying in the batwing and he wraps a cord around a villain's neck, chokes him to death and says something to the effect of "this scum's terror is over, he deserved it, etc." Nolan, like any filmmaker would, takes the parts from the original comics that he likes and leaves the rest.
