That seems like an unfair response. There are certainly still drugs in the peloton and there are a lot of teams trying to stretch the gray areas. But given the amount of testing and verification of those tests by reputable journalists it's unlikely that it would have the same impact it did in the early 2000's.

Training methods and nutrition have made a large impact on all levels of cycling in the past 10 years, and from personal experience I know that's certainly not all drugs.

Lance Armstrong was USADA tested 60 times, and likely hundreds more by other organizations, without a single positive.

It's all drugs.

The fact that someone cheated the system in the past is in no way proof that the same thing is happening now.

First it wasn’t just him. The entire sport has been plagued by accusations that the top performers are doping.

Secondly, he won 7 consecutive races. When he dropped out, the race times didn’t change that much and now the Tour de France winning times are faster than Armstrong.

You can claim that it’s better bikes, training, diet etc. The simplest explanation given all the facts though seems like doping.

Of course it's not proof of cheating, but it is strong evidence not to trust the testing unless something very fundamental has changed.

And your argument strongly depends on accurate testing.

Proof, no, but the best predictor of future behavior we have is past behavior.
