Why do you deny it? I point it out because it's obvious, and some on here are determined to deny the obvious, for whatever reason.
Men and women are different from one another, and yes, the majority of the time it is obvious. Those who try to convince themselves that we are equal, are blinded. There is absolutely no logic or science to back up the belief that men and women are equal. We're different. Some of us can compete with men on a physical level, but most women cannot. Why do you think that there are men's and women's races in competitions like the Olympics? Swimming, running, cycling, etc. They separate the sexes because the strength is not equal. It wouldn't be fair to make them compete with one another, because only a few women would make it. Instead, they bring the best of the women and the best of the men.
As far as psychological differences, look at how men and women parent. There are good and bad parents in both sexes, and this is not what I am talking about. I am talking about natural parenting techniques. The approach to parenting, and the approach to the child.
For more psychological evidence of our differences, look at the simplest things, like movies. The entire film industry is geared toward sexes. There are movies that are specifically made for teenage girls. There are movies that are specifically made for adolescent males and there are movies geared toward capturing the "dating" ages, between 16-26. These are the films that earn the most money. They're also the ones with the most violence, the most sex (aside from actual pornography), and the most money put into them. Males in that age bracket are the ones spending most of the money on movies, and though the female also enjoys them, if she were going alone with girlfriends, she'd likely pick another film. Psychological differences between men and women are no secret. All one need do is watch the commercials on tv during the day 9am-3pm. They're geared toward women. From 3pm-5pm they are geared toward children. From 5pm-9pm they are geared toward families with a stronger emphasis on the female. From 9pm-midnight they are geared toward couples with a stronger emphasis on males, and young males. From midnight to 4am, is when you find that the majority of infomercials are geared toward the dating age male audiences again, and all of the regular commercials are as well, so is the tv programming.
The majority of the $$ to be made in this world is based on the differences between men and women. People who don't realize the differences aren't paying attention.
