Women "becoming" men in the workplace

It's interesting to consider "not starting a family and focussing full-time on their career" as not feminine. I feel that that has only come to be defined as "not feminine" by virtue of it being valid and compatible form of femininity that patriarchal hegemony dismisses as being "not actually feminine" because it is a reality that goes against patriarchal thought that women "can't do these things". However, it is indeed important to allow multiple forms of people with many different forms and types of expression of femininity to be able to pursue a career (like, obviously). I feel like it honestly involves re-defining gender by traits and acceptability, eg. defining talking loud and sometimes over people in the workplace as a masculine thing (in our society, it is implicitly defined as such), and instead either define this behaviour as something that is gender neutral, or inexcusably rude.
