A guy who says “Not All Men” cares more about his own hurt feelings than the actual measurable, violent, systemic gender oppression faced by billions of people.
A guy who says “Not All Men” is used to the privilege of being treated as an autonomous and unique human being rather than an easily-stereotyped mass entity the way women routinely are.
A guy who automatically says “Not All Men” without taking even a moment to consider anyone else’s feelings but his own is absolutely “like that”.
