I think like others have said people have a lot more information now than they have ever had and the information/social media age has really ballooned at the same time as a 20 year period of whole scale blood manipulation has come to light.
However information isn't always accurate and neither is the analysis of it - you only have to look at Western news outlets to work this out. So broadly speaking you either take what you are told as gospel, question some of it or question all of it. Or jump to conclusions based on nothing but a hunch.
Most sensible people draw their own conclusions and avid cycling fans are simply cynical to a lesser or greater degree after two decades of what have now been shown to be a 90% doped peloton. This cynicism is only compounded by the fact that since the BP in 2008, claims by riders and the UCI that the sport is cleaner have been shown to be total BS. The UCI has tried to draw a line under it with the CIRC (that was then this is now, we are all clean etc etc) and the public are like "nice try, you are clean when we as fans decide you are clean", hence the behaviour at the Tour by previously duped fans.
My personal view? I enjoy cycling in 2016 (not as much as I used to) but I see it for what it is - a Professional Circus. The reality is that in all walks of life (including sport) people are looking for an advantage, it doesn't make it right but it happens and it will always happen particularly if there is money involved.
If you look back through cycling, it has always been a magnet for eccentrics and unusual individuals and as a sport it operates within its own bizarre set of rules, rituals, etiquette and traditions. Take safety as one example, its unsafe not to have a race radio but its safe to hold onto a car doing 60kph??
The biggest problem I see in cycling is its obsession/dependency on medical assistance legal, illegal, banned or not banned. The smokescreen of "physiology" has further muddied the waters as it creates a grey area of what is "legal" but a the same time questionable.
Even the big "clean" teams are pushing the envelope of "cleanliness". You only have to see the furore around TUE's with Sky the other year and they Argos Shimano documentary with a physician brandishing a fistful of "legal" medication to get riders to the finish line each day.
Why does a team of 30 riders need 4 doctors when the average human being goes to the Dr once a year if that?
What would a healthy individual say if he saw inside the bag of a Pro-Tour teams doctor and said doctor explained the various uses of medicinal products?
These are the questions that Brian Cookson should be asking.
