The two reasons I gave apply to handwriting and the cost of printing books, neither of which is applicable to the subject of this thread, and do not contribute to your rational regarding Karaoke screens.
Sorry I contradicted your "Preaching", but it is not a one shoe fits all situation which you deemed to present it as, nor will there be any right or wrong viewpoint in this discussion, which would only serve to make further discussion a lesson in futility.
