@djjd62,
I think some perspective would be helpful.
We know throughout history, women have been treated as second class citizens in most cultures. That they were not as productive as men isn't even a fair comparison - just as blacks were held back.
It's been shown through research at Stanford University that groups who are told they are not smart will perform poorer on tests, and those students who usually struggle will do better when told they are smarter.
When women and blacks have been told for generations that they are not intelligent, it really has an impact on the majority, and we all understand that they have been held back from opportunities and improvement for a very long time; most were even discouraged and not allowed to attend school.
Just saying "women are smarter than men," or "men are smarter than women" are based on ignorance as much as gender and racial bigotry.
