On an individual level (just again from my own experience) operating as if sexism doesn't exist, in general, and looking at each individual I have to deal with as an individual is optimal on a daily basis. But I do have to come up to 30000 feet now and then to strategize about the bigger picture -- sometimes to figure out how I fit in, sometimes to figure out what I might want to do to help others with their goals, sometimes to point out to a friend that what might cost me too much in the workplace would be easy for them to suggest. I'm not a VC, just a worker drone. Must be interesting to be on the investment side!
These are words to live life by.
What works for the 'person' often does not work for the 'people'.
Systemic inequalities only truly reveal themselves in statistics. Thus, an individual anecdote by a 'person' serves no purpose for a policy that's created for the 'people' what-so-ever. On the other hand though, those anecdotes are central to the 'person' and 'persons' who associate with them. Now, treating those same anecdotes with indifference can be catastrophic to your 'person'-al relationship.
It's how as a country I encouraging STEM as a policy for the people is a great idea. However, pushing/incentivizing your own child towards STEM when they clearly want to do something else is not so great.
As humans we need to compartmentalize the way we empathize, strategize and process emotions along the same lines of 'people' vs 'persons'.
