It's not hate, it's a reality that should be acknowleged. The best analogy I've heard is that a woman is like the most responsible teenager in the house. At first they mature faster than men because in the past it was common for them to bear and raise children while still in their teenage years. Men take a bit longer to develop because historically they defended the family and dealt with the outside world. The balance turns again in late life, after the men have died from work and war and the old mothers are still around to help the next generation.
