Why does feminism pursue equal rights between men and women, while sexism pursues male privilege?

Feminism pursues gender equality, and women can enjoy the same rights as men. But now, to some extent, women have more power than men. Now some women have a fixed view that I am a woman and I am a vulnerable group, so men should let me help me. I think this is a bit beyond my duty, that is to say, helping others is a kind of affection, not my duty. Pursuing male privilege is male chauvinism, which is also unscientific. Not all boys think so. Now with the improvement of education level and the popularization of quality education, most boys will respect girls, and this male chauvinism has gradually decreased.
