methodology and an assumption that all climber have the same ethic...you are talking about apple and orange. This is two different think. I said that your conclusion are biased by the fact that you consider that every climber have the same ethic.
I said quite the opposite. Setting aside the fact that you are saying "ethics" to mean the thing that I refer to as "norms", let's examine my argument again.
I said that climbers in NC are expected to establish all routes (sport, trad, aid, etc) ground-up on first ascents, and that in New England we are not held to that same standard. I also outlined a solid argument for why this is ethical and acceptable. That reason being that there is only one universal norm (or ethic, as you would call it) in climbing: to respect local tradition, style, and history.
"ground-up FA, versus rap-bolt a 5.7 slab. I am in front of my computer. I can decide to agree with the set of principles that I will do a ground-up first ascent or I can agree that I will do a rap-bolt FA. I am in front of my computer, it is all mental, nothing is style.
Oh for god's sake. Of course this is a mental exercise. If you're going to accuse me of arguing over mental minutia, then I say "I didn't start the fire, but I surely burned in it."
definition of ethic: eth∑ic (thk) 1. a. A set of principles of right conduct.[...]
3. ethics (used with a sing. or pl. verb) The rules or standards governing the conduct of a person or the members of a profession: medical ethics.
your definition of style and ethic look biased? what is the definition of style? and the difference between ethic.
Let's set the definitions aside and talk about the concepts.
When you say "bottom up mentality, it is more trad ethic and many people think that retro bolting is cheating" you are making an implication. That implication is "routes should not be rappel bolted." Any time you say or imply the word "should," then you are stating an ethical norm. You are making a rule for people to follow.
Help me understand: when you assert that people that they should not do bouldering before doing trad, and that people should not do sport before doing trad, there has to be a reason that you find this to be true.
Please, choose the reason that fits best:
1. There is a right way to learn climbing skills, and to deviate from that path is wrong.
2. There is a right way to learn climbing skills, and if you do not learn them in the right order, then it leads to chaos, gridbolting, and unsafe behaviors?
3. Trad climbing builds certain skills, and the climber who has those skills is more equipped to make correct decisions in future situations because they are a good climber.
EDITED: I originally said, "Routes should not be retro bolted" and I meant "rappel bolted".
