Estrogen is also a hell of a drug... It's actully a point in the article that people give testosterone too much credit and estrogen not enough credit when it comes to how they affect the physique.
Your argument being founded on the effects of testosterone is not a good one...
For example I am an average height and weight guy. I had never gone to a gym in my life, but at 25 decided to start powerlifting with some friends for fun. Within 3 months I was already lifting nearly as much as the world record lifts by women in my weight class.
I started going to my university powerlifting competitions, having lifted for less than a year, and was definitely lifting poorly compared to the other men, but I out-lifted every woman there most of whom had been training for years.
I don't think you understand the average difference in strength between men and women, it's rather large.
I don't think I'm arguing against your evidence. It's your idea that this difference in men and women's strength is simply explained by a difference in testosterone. This claim does not nullify the questions posed in the article.
Both biology and the environment play roles in defining people's personality and physique. Higher testosterone is only a piece of biology's role, but it's only loosely related to environment's role. It's not an unreasonable hypothesis to claim society's artificial rules placed on women might have had an effect on women's physique through things like sexual selection. This is why scientists still explore these things.
Testosterone is a hell of a lot of the explanation though. When people inject more testosterone they get a hell of a boost to muscle development and strength.
Although past sexual selection may have led to women being smaller and having less testosterone and ability to develop muscle mass, it does not change that women are indeed smaller and have less testosterone and ability to gain muscle mass than men, leading to the average woman being slower and physically weaker than the average man. My replies have been directed at the assertion earlier that men only hold records because of outliers, and the average man and woman are close in strength and speed, but that is just not true.
In that case, there may be a flaw in argument. Your anecdotal story doesn't disprove their point. The moment you started powerlifting training for 3 months, you've already became stronger than the average male. Most men on Earth don't do any sort of strength training, and it's not unreasonable to think that these men are not much stronger than the average woman.
And most women on Earth don't do any strength training, and are much smaller than the average man.
Hell I was way stronger than the vast majority of women I knew well before I started any strength training, my point was a few months of training had me on par with the strongest women in the world in my weight class.
