I am glad that you feel offended that someone would consider the possiblility of a cyclist, pro or not, to be doping, but get used to it. Your predecessors, including the federation which issues your liscence, left you with a sport that is a mess and you will have to grow up and deal with it. Berzin made very accurate statements about drug testing in cycling and specifically here in the US. A quick check of USADA testing shows that you were not tested in or out of competition once this past year. It is hard for anyone outside of the sport to accept blanket statements from people like yourself, who's livelihood is based on sponsorship that is highly influenced by public perception of what is going on in pro cycling.
I have 20 years and more than 1000 days of pro racing on you, and I gaurantee that my perception of the sport is more accurate than yours at this point. You say you see nothing. Good for you. I saw nothing either racing domestically, not a teammate or friend, however there have been what, 4 guys that ever held a UCI liscence that have been outed on Papp's list and I raced against 2 and with 1. I am sure that as the list grows so will the number of teammates and friends that I find out to have played both sides of the game. I am sure as time goes by you will relaize the same.
Good luck, train hard and be honest with yourself, your loved ones and friends. It is a beautiful sport, with some ugly people involved on all levels, even the fans. It is your job to deal with it.
