As ~always with gender and politics, there’s a pretty big gap between what is and what ought.
What is: The people who make and seek out men-only groups have a stereotype of being shitty, sexist people. The stereotypes around women-only groups are a lot weaker and less negative. These stereotypes are not rules, but do certainly lead to some social stigma.
What ought 1: In a better world gender-specific groups might exist for people to find support and connection around their gendered experiences. There’s some experiences that aren’t commonly shared across genders and it can be a lot easier and safer to share with people who you know also have that experience.
What ought 2: In a still better world there wouldn’t be a significant desire for such groups because we are all sensitive and caring enough that such a group doesn’t make sharing meaningfully easier or safer, because it’s already easy and safe.
They’re going to make this way too sensitive so people throw away even more food and effective prices get driven up. I guarantee it
