I'm angry because if we agree that that work was important (not sure I do, but not the issue), then the sacrifice of basically torturing a bunch of animals to death in service of science should be treated soberly, with reverence. I'm kind of baffled that you think that I, or anyone, should have no problems with the described conduct.

A surgeon, while operating with all diligence and conscientiousness, may from time to time kill a patient. That's life, it's table stakes to having surgery at all. The notion that it's cool if she jokes about killing the patient to "cope with her emotions" -- esp in an auditorium full of people -- is just fucking ... I dunno what to tell you if you think that.

Angry at himself for failing to publically point out and engage in discussion about the cruelty and terrorizing that was conducted, and well-understood by other science practitioners, and also the much of the audience present.
