The ones "whining" about Landis? Or about Armstrong? Yeah, they clearly didn't have a leg to stand on. Landis had obviously just had a lot of sex and whiskey after his collapse and then the good lord blessed him with a little extra man juice for the next day. Nothing suspicious there.
And I don't think there can be any doubt that a guy who was a great, but not exceptional, cyclist before his cancer could come back from debilitating chemotherapy and beat an entire field of dopers 7 years in a row... without being a doper. I mean, surely, if you don't buy that you're just a whiner.
