Yet, you hace describes how women face obstacles that men don't that make their choices not as free as they should (see the part about getting into debt only for a man getting the job). Sure, it is ok that some women want to be homemakers. It is not OK that they are presured and guiltriped (the part about being too tired to give anything to their families is this) into staying home is not free. Saying/implying that career women are bad moms is not free. Or that their choice is "unnatural" with the implication that "unnatural" = bad. All this is social presure that make choices less free.

So to answer you question, presuring women to be homemakers is sexist even if you honestly believe is good, because women are people and what is good for you migh be terrible for others. You might be presuring other women into miserable and bitter lives.

Instead, I suggest that you help the women in your family and friends the way you can, and take the help they can offer you. By removing obstacles to each other, you might feel less "attacked" by their choices and feel more comfortable in yours. Also, have a back up plan for when you grow old. Beauty and youth fades.
