That's a paradoxical thing to say, since you probably discovered him through his free soloing. You might not have been his fan had he not free solo'd.
But more importantly, it's probably better to let people do the things they love as long as they're not directly hurting others. Surely the feelings of fans shouldn't override the preferences of the object of their fanaticism.
I agree that nobody should be prevented from doing risky things. But when they become "famous" I believe it reckless to disregard the feelings of their fans.
