So the dude that holds the world bench press record wouldn't have made the same efforts as a woman? Would his lifetime of work not have paid of the same? Does the guys potential lie in his genitals or himself? And if we had the exact same life as him in every way, would he still be better because he as a person had that talent or is it all just biology?
And remember when people thought women were less intelligent than men? At the time results showed that. But once girls were expected to perform at the same levels, they have.
