Maybe the Brits have it right with their E ratings. That makes a lot of sense to have a pure difficulty rating, regardless of danger, then a seperate commitment or danger rating.
I also think that a lot of people involved in drilling these days act autonomously, away from the main established climbing community. These "ascenscionists" have learned their skills in a gym and are mostly ispired by the ethics that are popular indoors and on modern, steep, sport crags. They are ignorant about the values and rich history climbing has. Its one thing to drill a new route or retrobolt if your actions are premeditated, discussed, and accepted. But "renegade" drilling, espescially on protectable rock, is unacceptable and shouldn't be tolerated. There isn't a lot of mutual ground on this issue and this sort of thing shouldn't be validated by being passive or worried about aggression begating agression. It needs to be nipped in the bud.
