Sadly, you're wrong. For years the route to become a NASA astronaut included being a military test pilot. That position was not available to women, and so NASA prevented women from becoming astronauts.
They continued to do so even when testing showed that women were at least as good as men, and often better, and had other advantages. (Smaller, and thus lighter, and thus considerably less expensive to send into space).
I dunno, this seems kinda like the "racism is over" argument. As long as there are many, many people who (consciously or unconsciously) believe that nothing of value was ever accomplished by a non-white non-male, there's value in pointing out that they're wrong.
Nothing good will come of trying to forcefully change those peoples' minds. Because such actions are incredibly divisive, even if you sugar-coat it with noble ideals.
"someone wrote a blog post" seems pretty mild in response.
Basically, you're saying we should cover up any history that might make people uncomfortable?
But given the smartness thing, it turns out that IQ varies a lot by race. African Americans are the only race where IQ of women is on an average far better than man. (I don't vouch for the science here, I come from a country without concept of race and hence cant read racist context in academic articles).
I apologize for being nosy, but what country is that?
