The problem with Armstrong is much less about his doping, and much more about the manner by which he went after the people who dared counter his narrative. If he were just some other doper who was doping, then he would just be one of the names on the list. However, his actions towards people like Betsy, Bassons, Simeoni, and others has, for the most part, created the atmosphere here. You combine that with his "I had cancer, and other people have cancer, therefore you are not allowed to question me" media persona offends many people including me.
You believe what you want. You seem like a decent person who has questions about all of this, and that is fine. People have different opinions about every subject, and I understand your concerns. They do not sway me from my opinion, but I am sure you will not lose sleep over that.
