Perhaps, like me, he believes there is a place for both types of wild places, and a pressing need for advocacy for both? You have a quote from John Muir as your signature; honestly, which way do you suppose he would lean if he were alive today? You're upset because REI does not advocate for more motorized access. I don't expect the Blue Ribbon Coalition, or Toyota for that matter, to advocate for more wilderness. Both approaches make sense for the respective associations, and both are needed if we aren't to lose it all.
The real threats to all kinds of outdoor recreation (from both radical ends of the political spectrum) go unnoticed while we bicker over things like this.
