Hey, Sam here!
Misogyny is the hatred of women, specifically those of the adult human female body.
We live in a misogynistic society.
Misogyny is generally a male thought pattern and manifests in male violence against females (physical, emotional, financial, etc), rape, murder, forced reproduction, domestic abuse, wage gaps, work-related abuse, among much else that would fall under female sex-based oppression.
Internalization is a psychological concept, specifically one of social psychology, that is super interesting and I would encourage anyone to read up on it.
Internalized misogyny is misogyny that women have learned over time.
With repeat exposure to misogyny, role models expressing misogyny, misogynistic mass media, etc, the negative stereotypes and feelings towards women in general can become a part of a woman’s unconscious psyche.
This being a self-hatred of sorts as well as the hatred of other women.
In other words, a woman with internalized misogyny has incorporated male hatred of women into her self-image and the image she has of any other woman she comes into contact with.
This is externalized (the opposite of internalized) in many ways, such as competition between women, bullying and teasing of other women, physical/emotional attacks on a woman or her reputation (mirroring the behaviour of men), preference to befriend men rather than women, conforming to femininity, socially ostracizing women who do not conform to femininity, etc.
Conformity is another interesting concept of social psychology.
In a way, internalized misogyny is an insidious way for females to conform to the majority consensus (most males are misogynistic internally, if not externally), to “fit in” with the male supremacy, and attempt to stay safe on the individual level.
This, along with group pressure and dynamics, makes internalized misogyny difficult, albeit not impossible, to check and unlearn.
