In general I think it's morally wrong to not be against doping in sport.
But as a Cycling fan with no connections to cycling as an athlete myself I can partly distance myself from the moral question and the obvious "it's so unfair for the clean riders"-problem. As a spectator sitting in my couch the main thing for me is what looks and feel right. It's probably very much double moral involved, but for me as an spectator thinking about the entertainment value first (and not what is right or wrong) the eye test goes like this:
Does the rider look, act and feel like a Champion?
Remco look like a Champion. He acts like a Champion. It feels like he is exactly how a Champion should be.
Pogacar look like a Champion. He acts like a Champion. It feels like he is exactly how a Champion should be.
Van der Poel look like a Champion. He acts like a Champion. It feels like he is exactly how a Champion should be.
Bernal, Carapaz, Mas, Ayoso, Carlos Rodriguez etc looks like Champions. They acts (kind of questionmark regarding Mas here tho
) like Champions. It feels like they are exactly how a Champion should be.
It was the same when I was younger.
Boonen looked like a Champion. He acted like a Champion. It felt like he was exactly how a Champion should be.
Contador looked like a Champion. He acted like a Champion. It felt like he was exactly how a Champion should be.
Valverde looked like a Champion. He acted like a Champion. It felt like he was exactly how a Champion should be.
With riders like these I feel like these are the riders that would be among the absolute best also in dream world where doping didn't exist. It's probably just pure gut feeling and there is no proof to back statements like this up. It's probably just a defense mechanism to justify to myself why I spend so much time looking at and thinking about elite sport.
What I do struggle with is riders that doesn't survive the eye-test. Best example Froome. It's probably a bit unfair, but it's just I feel that it's an insult that I am supposed to believe he is the real deal. Because his whole story and how he look on a bike just feels so wrong.
