No, I am not the person you responded to, I just thought it was funny because all I could think of reading your comment was how many parallels it had to the “not all men” saying.
But to be more serious, I don’t think you can point to any individual saying men can’t discuss these topics, but there is a sentiment that has been felt for a long while. Listen to Bo Burnham’s Inside and he jokes about being a white guy trying to be supportive but not really being sure how without coming off as a “white savior.” A couple decades ago Ben Folds expressed frustration at not feeling allowed to express his personal problems to some degree in Rockin the Suburbs, and while that was more aimed at complaining from a place of privilege I think it captures a similar feeling the person you responded to expressed.
I think it’s difficult for a lot of men, especially younger ones, to express that kind of feeling without being (or feeling like they are being) rejected for having those feelings because they are the ones with the privilege. Or they may bottle up those feelings in an unhealthy manner out of guilt for potentially distracting from those with bigger issues. And those can open the door to them rejecting feminism in general so that they can express those feelings. People like Andrew Tate are able to take advantage of that.
Humbling? That’s going on in my head. I’m that complicated! Or at least the “hardware” I run on is. I think having a brain that beautifully complex is more empowering than anything! I wonder what new discoveries will stem from this.
