I don't think it's as ominous as all that. "Care" is supposed to be the worries and stresses of work. Which makes since, because Bohemian Grove is just a vacation for wealthy Republicans.
Besides, it's not as if they need to be reminded not to care about the plebes.
Now, if you want a middle ground, just ask Rodents of Unusual Size (source: http://www.poetv.com/video.php?vid=97329 ).
(memdumpster) "How can owls be a symbol of evil? I never understood that."
"They represent death.
So it gets interpreted as evil. Really the owl symbolizes the death of the cares of the rich elite, according to all reliable reports. They burn the effigy to symbolize how they don't have to really worry about anything because they're in charge. It's incredibly egotistical and psychologically disturbing, not to mention repugnant.
