Excellent first post. Welcome to the forum.
How's your mixed martial arts training going, for when the strong armed bully shows up?!
I think we've all come across many of those. I'm finding now that many of these people, once they get over the shock of the SI article, may accept it's likely he doped, but are taking the "innocent until proven guilty" approach. That it's all just heresy, and doesn't prove he did anything until he's convicted in court on hard evidence. And that talking about it without that evidence is unfairly destroying his reputation, etc.
Usually these people also refuse to look deeper into the issue. If they are willing to read it, I usually first send them the Michael Ashenden interview, the Nightline special, or Walsh's book. But most of them seem to willfully not want to know more. They think they are being impartial, and we are being judgmental, but without saying so directly they refuse to look deeper into the matter, and rationalize reasons for not doing so.
