I've run into a few Camino Snobs lite on my Caminos. Not the "I'm better than those that haven't done the whole 800 km" type, more the "I did 800 km, which they didn't" type - a slight difference, but a difference nonetheless. And, I have to admit, I took advantage of my distance upon entering O Pedrouzo when bunks were in short supply (but there were some reserved for the long-distance walkers)
I always felt awed by those that did more, starting out in Switzerland, Paris, Denmark, or other places. It always served to keep me grounded, that despite the fact that (on my second Camino) I started in SJPdP, it still wasn't the distance they had covered.
Having done my first Camino with my wife, who was still recovering from a near-fatal auto accident, and could barely make 12-15 km a day on an ankle that had previously been shattered (and that was only one of the many broken bones), perhaps my attitude was a bit more accepting of the Sarria Strollers than some of my longer distance Peregrino companion on my second Camino. When they would comment on the short-distance Peregrinos, I would simply say, "Hey, they're out here doing a pilgrimage. It's their Camino. They could be doing something else, but they're here." I think many of the ones I spoke to came to that realization. We're all on the Camino, just some of us were on it longer. That doesn't make our Camino any better, any more special (all my Caminos have been special, in their own way), or any more spiritual, it just makes it longer
.
I take pride in the fact that I completed a fairly lengthy Camino. I consider the first, short Camino, to be one of the most uplifting things I ever did in my life (despite being only 117 km and 10 days or so). I could only hope that others get that same feeling, regardless of the length of their Camino.
So, if somebody's a snob, gently remind them of the purpose of the Camino (it ain't about length!). If they don't get it, move on.
And if somebody "cheats" on their Camino, does that lessen your experience? I know it didn't affect mine. I did my Camino for me (well, technically, In Vicare Pro for my parents, but you probably know what I mean)
Buen Camino (regardless of how long or short).
