When you said it, if you did not believe in what you said, you better have not said it. The world is filled with enough empty smalltalks. Moreover, if even you do not believe in what you say, who the hell would believe in you ("read you") next time you say something?
If you thought it was right but have changed your opinion in between, please state it clearly. It is a strong mark of cleverness (to me).
If you still think it is right, please stand for your opinion, it may have some value for others.
