The difference is that shitting on men is acceptable. At worst it's venting a bit. And collectively attacking men is fine.

Not like saying something negative about a woman, in which case you have to be very absolutely clear that you are only talking about that one woman in that one scenario and that it is in no way representative of any other scenario or woman, and even then you'll be accused of misogyny.

But then this notion that it's OK to talk shit about men but women are either positive or victims at worst shows in a lot of feminist lingo.

For example, what do you call it when a company markets a version of a product specifically to women and charges a higher price in doing so and women buy it? The pink tax. What do you call it when a company markets a version of a product specifically to men and charges a higher price in doing so and men buy it? Male fragility.
