I think any cultural bias takes more than a generation to go away. As hard as anyone tries to make a conscious effort, millenials have been brought up by people who were still to some degree perpetuating ancient prejudice against given groups of people, which did impact them as a child in pernicious ways. The key I think is to try to recognize one's biases and work towards keeping them in check, while working proactively to smooth the social rapport with all other human beings, so that newer generations will in turn be less impacted by said sexism, racism, etc.
