I think it is funny. I enjoyed it because like most good humor, it is a playful exaggeration on patterns that exist on real life. Sometimes those patterns break along racial or gendered lines, and that's ok. You're not a bad person if you think it's funny. I get laughs out of lighthearted humor that pokes fun at men as well.
Are they really patterns, though? Or is it confirmation bias?
Even early psychological studies from 100+ years ago found that women, on average, feel and react to emotional stresses the same way as men. There are 100+ year old studies on PMS that say women, on average, don't express more anger or sadness prior to or while on a period - and yet we still get hysterical women PMSing memes.
Media can make us see patterns that aren't there. Media can change the way people view the world around them and affect how they behave.
I think it is a trend that men in general are less inquisitive about each other's personal lives and discuss them less often, yes. I don't think that's an inherently good or bad thing but I think it's true. Also, it's worth noting that the "PMS mood swings are a social construct" theory is still listed as an "Alternative Theory" on the Wikipedia page and the handful of women I've talked to about it have all said no, the mood swings are definitely real.
Don't let me get in the way of what you think, or what wikipedia and other women have told you. I'm basing basing my comment on the psychology courses I've taken.
It's important to not that research on PMS has been fraught with medical, historical and personal biases. This is a very well done article on why the issue is incredibly nuanced: https://www.ncbi.nlm.nih.gov/books/NBK565629/
The other reason this is a sore spot for me is because I am a woman who lived with undiagnosed mental and physical disorders for over ten years because my complaints were disregarded as menstrual symptoms. I was eager to internalize that because of prevalent media that pushes the idea of the hormone-driven, irrational female, without providing the basis for those claims.
As it turns out, being in a whole fuck lot of pain and having doctors tell you that's normal can make someone pretty irritated.
I'm with you but just for the sake of hypothesizing an answer, it might be that those who like it or don't think too much about it just read, upvote, and move on. While those who have comments click and share.
It sarcastically describes my life as a man, especially when I try to be the top two people but every other man wants to be the bottom two. The title might glorify it but we aren't.
