Cat calling isn't coercive control and neither is fashion design that is hyperfocused on women who are size 2. That doesn't mean that other negative societal forces aren't in play. As a social scientist I'm well aware of the implications of these, but they aren't the same kind of coercive control that a partner, family member or employer has the ability to exert and I think it's important to speak with precision.
Cat calling, for one example, is a dominance posture that is inappropriate - but it's not coercive. The harasser wants you to feel intimidated, to feel objectified, etc., but they have no actual mechanism for ensuring that you will or for making you suffer if you don't. It doesn't mean it's not distasteful and wrong, but there is no coercive component because they have no way to force you to do anything and there are no repercussions if you fail to do what they want.
