I don’t believe that you can make a comment as sweeping as “most Bay Area women... are so useless you could trade them for a jerry can of diesel” that doesn’t reflect a stance on all women.
There are 7.75 million people in the “Bay Area”, presumably about half women. The idea that you could believe nearly 4 million women with totally disparate histories - only united by currently living in the Bay Area and being women - are mostly useless without making sexist generalizations about women defies credibility in my view.
And I used the word “most” because his quote begins “most Bay Area women are soft, cosseted, and naive...” so you’ll have to ask him what he means by “most”.
