As no one else appears to be commenting on the cat fighting occurring on this thread, I will. To me Zooworker is "pleading" with Patrick to end this debate with emphasised requests for his "stupidity" to seize. This could possibly be because he is drained of this debate and wishes to participate in the discussion of Taronga without persistent antagonism in which he is entitled to do, or something more sinister; like releasing someone (Patrick) has uncovered his fake ID and is desperately attempting to persuade both Patrick and the forum users in general that he is not an imposter- in order for him to maintain the powerful alias of being a Zookeeper.
On the other hand, the resume and general knowleadge of the seal program's history and status at Taronga Zoo are both fairly convincing; while Patrick's agrument seems to have become less persuasive; possibly due to a defence finally being installed by Zookeeper which has affected his ability to conjure brilliant rebuts in turn.
I find Patrick's point that Zookeeper failed to deny his accusations twice especially suspicious also; as I noticed this in another dispute between the pair (don't know date or thread), primarily a one way dispute (Patrick to Zookeeper). It is interesting how Zookeeper has avoided confronting this issue until now. I can't see how "representing a large institution" can prevent someone from maturely dismissing these claims. Sure, an enraged attack which Patrick expected may not be appropriate for someone of Zookeeper's supposed situation, but a relatively level-headed rebutal (which was eventually delivered) surely could/would/should have been used immediately.
Prior to today I actually agreed with Patrick's accusation of Zookeeper being an imposter. Now, I've been slightly persuaded to believe Zookeeper's argument. However, as I do love a great conspiracy, I will remain on Patrick's side of believing Zookeeper is an imposter.
Also: If I am not mistaken, Patrick has mentioned he will be travelling to Sydney and subsequently Taronga soon. To settle this dispute, why don't you 2 just arrange to meet? I mean, if Zookeeper actually works at Taronga it shouldn't be difficult for anyone as you will both be there simultaneously (unless Zookeeper incoveniently (or conveniently?!) does not work the same hours of Patrick's intended visit).
