I guess it is unlikely we will find common ground then. I usually hate the phrase "agree to disagree", finding it's a cop-out, but here it seems appropriate. I can admire the sentiment and the passion, but simply think it is not realistic without some reforms in testing and due process, and massive efforts in athlete education. I see it similar to the death penalty in the states: even the threat of death is not a very effective deterrent, and the cost of getting it wrong is irreversible.
Divine right is a bit much. Don't forget that athletes are still banned -- it's not like there are no penalties today for doping. And just a few years back, penalties were even more lenient.
You can't really compare sports to regular jobs.
If I get sick, and go to the doctor, and he prescribes me drugs, I don't get fired from my work.
If I start bodybuilding, and take legal over-the-counter supplements from GNC, I don't get fired.
Athletes are in a difficult situation, where even if they try to stay clean, doping can often be inadvertent.
These are not rare cases in the fringe: "Athlete Ombudsman for the US Olympic Committee (USOC) John Ruger said that between 40% and 60% of US doping cases are inadvertent".
That's in the USA where awareness of anti-doping obligations is pretty mature.
I assume you are not familiar with the cases I've mentioned. It's not just the athletes who said they were innocent -- according to experts who reviewed lab results after the fact, the WADA labs made clear errors that led to declaring negative results positive. The adjudication process makes it very difficult for athletes to get the raw data, or a true independent opinion. Before any lifetime bans, lab error rates leading to a false conviction have to approach the limit of ZERO.
The sport took the biggest hit in credibility thanks to Diack and co., "colluding with the Russians". Would you punish just the Russian athletes?
I often wonder what people expect track and field to become -- outside of the Olympics, it's not like it is a popular sport generating revenue like football, basketball, baseball, soccer, rugby, cricket or cycling. Most track athletes live in poverty. And its not like any of these sports are clean, or work harder than athletics to keep their athletes clean.
And I wonder what sport banned athletes should go to? One that allows doping to defraud their competitors, sponsors and fans?
And finally, here are some reasons why lifetime bans will not work:
