I must reply to all of these ethic debates. First of all the existance of climbers impacts the environment and the existance of new standards that overrule the old standards create contraversy and make more than one side to an ethics issue and that also impacts the environment because people act in the best interest of themselves and not the environment. I believe that in the best interest of the environment we shouldn't have fixed protection in the first place, but in the best interest of my life and my ability the bolts should stay. But if a climb can be rated in "Aid" but not freeable than leave it the fuck alone!!!
There are plenty of free routes.
