As women, we are constantly policing other women. If she puts on bold red lipstick, she's looking for attention. If she's wearing a sleeveless dress with unshaven arms, she's trying to make an unsightly feminist statement. If she doesn't smile often, she's too uptight. If she makes a good presentation, she's trying to make other women look dumb. All these are instances are examples of internalised misogyny which makes women despise one another for irrational reasons.
