The parens were a reference to the "not all men" phrase from the me too movement, and the "yes all men" response.
It's making fun of that sentiment. That all men are the problem is as stupid as thinking that all women are the problem. People who have suffered violence from men, or emotional abuse from women will put up walls, and sometimes it becomes a wall based on gender. You missed the point.
I'm not invalidating what you're saying. I'm explaining why you got downvoted to all hell, and what you're interpretation edit may be missing.
