Human beings are not separate from Nature. We literally cannot live in a concrete world. Our continued viability as a life form depends on our protecting other species, most of which haven't even been discovered yet. Only those who choose to remain ignorant pooh-pooh this situation. In the light of this reality, I don't think that bicyclists who run stop signs, stop auto traffic, and ride on the freeway give bicyclists a bad name.
Nice bicyclists finish last, just as nice species become extinct.
What we are asking for is not radical. It is essential. We are right. Our anger is righteous. Our disgust is justified.
