I'm not offended by anything said and I've been choosing my words as carefully as I can so I'm not mis-interpreted as getting personal or offensive. I like the mental gymnastics.
"Leave no trace is an ideal that none of us ever achieve. Each visit to the wilderness results in an impact. The act of driving there is an impact in itself. Do you bicycle to the Sierra? That sort of Göran Kropp approach would impress me as much as your willingness to carry your feces for days at a time."
Seems hyperbolic to me. "leave no trace" and "Pack it in, pack it out" are really very simple concepts that do not include bicycling to the trailhead. They're merely an approach to being more sensitive to the fact that the mountains we recreate in are not capable of dealing with the volume of abuses humans have subjected them to. Changing our approach to minimize our impact is the key concept. It's really very simple. As simple as packing out a bit of poop.
""Weight does not matter at all." You can't be serious! This is only true if you are preternaturally strong like Norman Clyde or are simply strolling through the backcountry. For most people it matters a lot. For some walkers it's everything. There have been many trips I simply could not have contemplated doing were it not for the diminishing weight of my pack."
Are you being serious here? Really, we were talking about the weight of wet coffee grounds. If somebody is willing to pack it in, they should be willing to pack it out regardless of its new weight. If not, leave it home. This is not about all of the other decisions we make to minimize our loads, its about responsible trash removal and how coffee grounds play into it.
"Cooked versus uncooked rice weight has roughly the same water absorption as you get in coffee grounds. Maybe you like yours soupy? Rice soup is actually a very nice Thai dish."
Interesting. My rice absorbs twice its volume in water. My coffee grounds don't do nearly that. Even if they did, my argument would not change one bit.
"I'm glad you see it as a line to be drawn and not black and white as your bumper sticker slogan could lead one to think."
If you can pack it in, you can pack it out is very black and white. Leave no trace is an approach well written about in our community. They're not bumper sticker slogans.
For me, personally, I hate that coffee pouch stuff and I hate instant coffee, but I'm not willing to drag around wet grounds or extra kitchen stuff, so I drink instant swill- sigh, I love good strong coffee. I never intend to have leftovers to drag out, but my appetite isn't always there. So, I often carry out the extra along with the poop. Regardless of it all, my bear cans are much lighter when I leave that when enter.
