Rick Sinnott's argument against SOME single-track biking trails was predicated on data, decades of experience with wildlife and concern for public safety and wildlife conservation.  The fad-bikers' arguments have consisted of tantrums, logical fallacies and the "yeah, but..." reflex: i.e. they can't counter factual argument with facts of their own, so they ignore it, say "yeah, but..." and repeat their original stupidities.  Goebbels' opinion to the contrary notwithstanding, merely repeating a specious argument doesn't make it true.

Tim Woody's argument combines both the logical fallacies of false equivalency and deflection.  Soccer or baseball fields are built, but not in high-density bear forage areas.  Outdoorsmen hunt and fish, but most actively seek to AVOID adverse bear encounters.  Exceptions are idiots who fish in Brooks River National Park--and are heartily despised by the rangers there--and these self-entitled fad-bikers who confuse "recreation" and "thrill-seeking".
