“The idea of wilderness needs no defense. It only needs more defenders.”

As stated in, On the Defense of Criminals, an essay by Jay Leiderman. http://jayleiderman.com/blog/on-the-defense-of-criminals-an-essay-by-jay-leiderman/
Variant: It is fashionable always to cast aspersion upon those that defend persons accused of committing crimes. The viler the accused crime, the more vigorous defense the accused needs, yet, at the same time, the more vitriol the defense attorney will face. I cannot speak for my brethren in the legal community, I can only state that what follows my own brand of patriotism; I defend those charged with crimes because it is both my duty as a lawyer and as an American. Each piece of resistance to the encroachment of overreaching governmental power is, and of itself, a victory for freedom.

... While we await the precise moment when all of capitalism's victims will indignantly rise to destroy the system, we are being devoured. ... Some of us are going to have to take our courage in hand and build a hard revolutionary cadre for selective retaliatory violence.

The Future of Ideas (2001)
Context: A time is marked not so much by ideas that are argued about as by ideas that are taken for granted. The character of an era hangs upon what needs no defense. Power runs with ideas that only the crazy would draw into doubt. The "taken for granted" is the test of sanity; "what everyone knows" is the line between us and them.
This means that sometimes a society gets stuck. Sometimes these unquestioned ideas interfere, as the cost of questioning becomes too great. In these times, the hardest task for social or political activists is to find a way to get people to wonder again about what we all believe is true. The challenge is to sow doubt.
