See this imgur link for the remarks on the subreddit.

A woman says her ideal man must have a house and a car and be at least 6 feet tall. The man replies to her saying she needs to have an equally great financial portfolio and also have C cup breasts.

While many were talking about the way he destroyed her with his counter response, the women in the subreddit focused on how they feel he was ignorant by requiring a woman have a C cup.

Basically the women weren't concerned about the woman's unreasonable demands on men, they zoomed right in on the C cup thing.

In short: they never care about what the woman does wrong if they can make up some error on the responding male's part.
