After reading the first 5 pages of that thread, I don't see PIJAC mentioned once. I see a bunch of people speculating and repeating that Wyatt left, that there's a new organization he's starting and it might be good or it might be bad...
In other words, the thread is the same as people here who are asking "Gee I wonder what REALLY happened?"
I've never once seen PIJAC say that they were not in support of hobbyiests or private breeders. I've never once seen USARK say anything like that either.
I have seen certain people claim both, without proof or quotes or anything coherent. The fact that the few species were put on the Lacey listing despite all efforts of the herp community doesn't mean that anyone in the herp community "made it happen" or "threw them under the bus". It means we all failed to win a defeat, and the only reason it's only those few(instead of all reptiles), is because the committee members knew they'd face legitimate challenges legally if they banned everything at once.
