I'm familiar with the term "vivisection." I guess you could say animal abuse "triggers" my anger, but I don't like this term the way it's often used. I don't think things that make you angry are triggers. I think things that cause an episode of your particular mental or physical illness should be called triggers. When you get angry over something, except perhaps for people with rage issues, it's a normal reaction to be angry. I think of a trigger as something that sets off a panic attack, a "spell," pain to an injured area, etc.

Anyway, I'm wandering off-topic. I can discuss vivisection and animal welfare and abuse. I just signed a PETA petition, even though I'm not a PETA member. It was to stop horrific animal testing at a major college.
