Note how he only answers certain posts as he knows he is completely blown out of the water by facts. His completely crazy statement about cortisone use just started it.
It's a fact cyclists did use cortisones (not just tests, but also public statements from people like Fignon). When he just refuses being called on that it should stop here and now. After that his claim that no cyclist associated with Ferrari was caught was easily refuted. Now he starts moving goal posts... (because yes, his central argument did become that Ferrari was just a coach).
It's fine to have a different opinion, but when people start to deny open facts like those he stops being a serious discussion partner.
