Why men aren't being discriminated against?

Men have always been seen as the dominant group. They have always gotten the right to do things that women can't. Back then people saw women as just servants to men just because they were women. They thought men had a rational sense of making decisions. Men have always had the upper hand, and you notice that most rulers in other countries were men. For example just like the U.S, women had to fight for women's rights because they didn't have the equal liberties as men. Men are seen as the superior group.
