I brought up an example of a specific sexist and controlling behavior I observed (guys holding their wives or girlfriends by the neck while walking across the street, like they were steering a chicken) in a meetup group and all the men around me said they had never seen it. The two women said they both had experienced it.

Repeat this a thousand and one times with other behavior I and presumably you, as men, will never have to experience but are just as real.
