Comment from this context? http://itre.cis.upenn.edu/~myl/languagelog/archives/004434.h...

Is the point that "The problem with symbols like this that do not form part of a well-defined system is that people will see what they want to see."?

Meaning that oil companies will create a reality that matches their business or that the global warming alarmists act like religious zealots? I believe both are true...

What I mean is that a denier is a medieval coin.

Hmm. I was close :-P
