Why is the concept of feminism SO HARD for people to grasp?

If she chooses not to identify as a feminist that’s her choice, but she should just say that.

How in the world did she go off the rails? Nothing she said - none of her opinions or observations - conflict with identifying as a humanist.

From Wiki : Humanism is a philosophical and ethical stance that emphasizes the value and agency of human beings, individually and collectively, and generally prefers critical thinking and evidence (rationalism, empiricism) over established doctrine or faith (fideism).
