No, its an argued case that you don;t agree with.

Repetition of your case:

*should*, *normal*, *need weeks*.

IMO your argument boils down to: it tkes a *lot of time and effort*
fighting off book cracks, so we *should* be *moral* and use a *normal
book*.

1. IMO it is impossible to exhort the mass of programmers to this
position, therefore one or more will break it (intentionally or
otherwise).

2. The 'moralising' is out of place. Since all the opponent program is
doing is adding chess knowledge to his program - this cannot poissibly
be an immoral act.

3. The definition 'normal book' is another 'morality' exertion. What is
normal ?

The effect of this entire argument is to attack and humiliate Mchess and
supporters - that's actually the imorality.
