I don't get the thing one sometimes hears about the Tour-viewing public having been 'conned' or 'cheated'.
I said that people feel conned so I suppose you are making a point about the naivety of someone like me.
When you look back in the thread, often you see that people who now condemn LA freely admit to believing he was clean. Many LA fans actually think he is/was clean. Until recently this was still a controversial position regarding LA... because the whole LA story goes beyond the bike, indeed it wasn't about the bike for many people, but about the inspirational cancer story told to many people who didn't really know much about Pro-cycling.
I'm sure you're aware of this really.
When I started watching TdF in the late 80's, I was a young teenager watching without much knowledge of the history of the sport. I didn't think about it because I really didn't know of the existence of doping.
I don't think every sport in the world has had pervasive drug abuse. Perhaps naive, there you have me, but I suspect I'm standing with a lot of people and I find it odd you don't perceive that.
Edit : I'd go beyond this and point out that many of the stories of young riders entering the pro-ranks in the doping years were stories of disillusionment as they faced the reality of how much doping permeated the sport. It was news to people such as David Millar.
