"A slightly different standard of proof applies to the existence of Saquatches in the woods based on a few probably fake footprints, "

Absolutely Tom! Nail on the head! In fact there is more(standards to meet)! Nobody goes and justifies the organized slaughter of 10-15,000 people unless they has set and met a high bar for the justification of such slaughter.

Look, itrs still Yeti reasoning because
1) Absence of proof just leads you to claim we should look harder, they are hidden better, or theyu were moved (conspiracy) to Syria.

2) There is 'Good Reason' to believe in such things- because they existed only recently. (Yeti and fossilized Giant Apes that went extenct only in the last few 10,000 years)

"Let's say you went into the woods, and found thousands of old eroded Yeti footprints, old Yeti bones all over the place with a primate genetic signature, old Yeti hair on branches, nests in trees, and animal carcasses that had once been chewed by primate fangs, but none of this evidence was less than a couple of years old."

Yes, but the current and pre-war evidence for WMD is not even of this character. Its the say so of the Kurds, shady one-way-or-the-other satellite photos and INC defectors.
