Until someone provides any evidence that the Scheunemann scenario is false, it remain in the realm of possibility, and is therefore fair game for speculation. The only person who has advanced an actual argument on this subject is the one who is dismissing this scenario out of hand. Since arguments require facts to support them and speculations and opinions don't, the person who is making the argument that the Scheunemann scenario is false is the only one required to provide any evidence.

So far this person has not provided any evidence whatever. So we may dismiss that person's argument as having no basis in fact.
