This is a question I've thought about a lot
Many times people tend to shrug it off, because it's often mentioned to distract from women's struggles with gender roles
The sad thing, that's usually the only time it's mentioned. Not many people really care.
I think it's easier to judge men because of their place in a patriarchal society. If you judge them, it's not going to make or break the fact that they generally stand above women.
I'm not saying it's okay, but I think that's the line of reasoning, at least from what I've gathered with the conversations I've had about gender roles and from people who "hate men"
From what I've seen, men generally have more of a freedom. Yes, they are expected to be the breadwinners and may not be looked at the same if they're not, or decide to be a househusband, but they're not gonna face the same challenges as women would when making a choice to defy gender roles, such as being put down in the workplace.
They're both problems and should be talked about, but it's "more acceptable" to judge a man because he just won't have as many obstacles (stemming from his sex/gender) than a woman.
At least from my perspective... idk if that made sense cause I jumped around a bit
