She is actually half right, men are more likely to be found at the bottom end of the IQ ladder, but they are also more likely to be found at the top as well, whereas women concentrate more frequently in the middle.
Despite the fact a lot of men are retarded, their academic presence is still required to drive societal progress because they are the far more likely to be the ones to make scientific discoveries. This is true regardless of the fact low IQ thugs who perpetrate most of the crime in society are almost always men. A hypothetical society of only women would likely have less conflict, but it’s technological development would also be far, far slower.
