The situation has improved pretty remarkably -- I was open in my belief the program was drawing to an end and, if it were to continue, would be altered. I still feel that it was a reasonable conclusion based on the evidence available, and the way that most zoos seemed mum to communicate if they intended to acquire more animals or if negotiations were ongoing. I do wonder if there was a reason they were not able to state these intentions in public.
Read this article and found it fascinating, but especially the example about two young pandas 'bullying' each other, in that it showed there is more to this toxic fanbase than the nationalism that felt implied in the Memphis example -- clearly, there is something deeper involved that I had underestimated.... and of course, new proof that any fanbase or hobby can become toxic.
