I think that the intent of this restriction is honorable, but the scope is too inclusive. As you note, without debate and well articulated criticism, how are we to make arguments or voice our opinions (even if incorrect)? I, for one, enjoy some of the debate, yet also concede that some of it does turn into flaming or is initiated as a troll. There must be a distinction between wasted bandwidth wars with a hundred messages and debates/discussions that require some point-counterpoint argumentation. This forum should not only be for offering assistance, but also for having discussions (that remain on-topic anyway).
