EDIT: If you think that saying “Not All Men” is sexist or even problematic in any way whatsoever, then you’re absolutely crazy. You’re an absolute lunatic if you think that reminding people not to generalize and blame an entire 50% of the population for the actions of a few is something that we shouldn’t do.
When they are untrue, imo, it becomes valid to bring up “Not All Men”. Point #5 shows this. Point #5 basically argues that there are no “good guys”.
Well, I mean, it is true. Every human being on this Earth is susceptible to bad behavior. It’s in our DNA. It’s why we have civilization. You, me, and every man on Earth are susceptible to objectifying women and giving in to bad social constructs.
I disagree with your framing that there are no “good guys,” as you put it, because there are good people in the world. There’s good men in the world. But every good person is susceptible to evil, just as all evil people are susceptible to good.
Then why frame it as a problem with masculinity? I don’t buy the “it’s a problem with the human condition” argument, if that’s what she meant, she would have said it. I think it’s very clear what the author is saying—by the very nature of being a man in the western world, you do have problems with women in some form or another.
