" Despite my efforts, the movement abandoned science and logic somewhere in the mid-1980s, just as society was adopting the more reasonable items on our environmental agenda. Ironically, this retreat from science and logic was partly a response to society’s growing acceptance of environmental values. Some activists simply couldn’t make the transition from confrontation to consensus; it was as if they needed a common enemy. When a majority of people decide they agree with all your reasonable ideas the only way you can remain confrontational and antiestablishment is to adopt ever more extreme positions, eventually abandoning science and logic altogether in favor of zero-tolerance policies.
