The only experience I’ve had similar to the one described in the initial post was a few summers ago in Glacier Peak Wilderness (Washington). What was most odd about it was that the “shaming” didn’t even involve gear, but rather what the purpose of my backpacking trip was.
I arrived at a small subalpine lake fairly late in the day (it was about an 11 mile hike in with around 4,000 feet of elevation gain) and there was a group already there, but plenty of places to camp in the general area. I had to hike through their camp to get to the other campsites and, after exchanging general pleasantries, a member of their group asked me if I was planning to climb a nearby peak the next day (the area I was in is popular with climbers, but not so much backpackers because of the rough approach).
I replied, “Nope, I’m just going to check out some of the nearby lakes, do some fishing, and I might head up one of the smaller unnamed summits on my way out”. What he said next, in a somewhat condescending tone (at least that’s how I interpreted it), caught me off guard: “That’s a long way to hike just to look at some lakes”.
I waited a few seconds to reply, as I was surprised at the implicit judgment and absurdity of his comment, looked around at how beautiful the place I was in was and how trivial the conversation I was having was, cheerfully replied “Yeah, I suppose it is. Have a good evening!” and continued on to camp.
He seemed as surprised at my reply as I was to his. But he wasn’t wrong. Objectively, it was a ways to hike “just to look at some lakes”. And I wouldn’t have been wrong to reply “Yeah, it’s a long way to hike just to climb a mountain, too.” But looking back I’m glad I was able to just shrug it off as one person thinking their hobby (climbing) was superior to mine (backpacking) and perhaps trying to show off for the women in their group.
