If you at all accept that there are harmful but culturally ingrained gender roles
The problem is that all too often those harmful gender roles are only called out as being harmful to women, not to men, but they are. The solution to the gender roles issue is not digging trenches between genders.
The point being made is that you won’t solve the issue if you divide society between men and women, instead of normal people and sexist bigots. The point is not to replace existing harmful sexist stereotypes with your own sexist stereotypes, but to come together and listen to each other.
