I think that's overblowing it. 99.9% of the time, trad climbers and sport climbers and their respective ethics coexist peacefully. There are rock climbing areas that are better suited to trad and areas that are suited to sport, and most of the time those areas are pretty well agreed upon. There are also areas (such as Yosemite) where a mixture of removable gear and permanent gear is most appropriate and in those cases, the general rule of 'removable gear where possible, fixed gear where necessary' is also well agreed upon.

What you're talking about with Harding and Robbins on the Dawn Wall is a clash of ethics that is long in the past. Very few people consider it worthwhile hammering pitons into a slice of blank rock in order to ascend it and aid climbing in itself is less popular with respect to free climbing.

> A year later, Royal Robbins made the second ascent, chopping off the bolts as he went.

un-devmox said that Royal Robbins stopped (https://news.ycombinator.com/item?id=13015150), and Wikipedia agrees (https://en.wikipedia.org/wiki/Royal_Robbins#Dawn_Wall). (Technically, I guess neither of those contradicts what you said.)
