The problem isn't skeptics, it's the lack of evidence. The problem with a belief system based solely on sighting reports is apparent when you ask yourself what you don't believe. If you truly feel that Sassy exists because of unverified sighting reports then you also believe in Chupacabra, UFOs, Elves, Fairies, Dogmen, Jersey Devils etc, etc. You can't argue for the existence of Sassy solely on the strength of a sighting database yet argue against the existence of Ghosts, Wendigos, Skinwalkers, Lizardmen, Alien abductions or the like which also have their own databases. If you don't require hard evidence you believe in stories.
If your belief in Sassy is rooted in the strength of an unverified database you and your arguments for existence are not relevant. You will never advance the field, you will never prove anything, you will always be disappointed in the outcome of discussions. Science and skeptics have the high ground - they admit that Sassy is possible yet unproven. Understand that although a few scientists believe in Sassy the vast majority do not and never will without verifiable samples. There has been a lot of testing recently and none of the samples returned any positive results. That doesn't mean it's impossible for Sassy to exist but it does mean that whatever sighting report the sample was collected from is suspect. It should raise even more doubts about the database itself - there is no other logical conclusion.
It's frustrating to believers and skeptics alike to have hoaxers and con artists operating in this field. It's even more frustrating to have an interest in the subject and be open to the possibility of an unknown creature but have to wade through thousands of posts which argue for the existence of a creature solely on the basis of anecdotal stories alone. We all know stories don't prove existence, we all know stories will never prove existence, and we all know that anyone who continues to argue for existence based solely on stories isn't even relevant to the discussion.
The problems in this field aren't caused by skeptics, they are caused by believers who don't, can't, won't get with the program. Stories won't do it, it will take evidence.
