"Most women in the Bay Area are soft and weak, cosseted and naive despite their claims of worldliness, and generally full of shit. They have their self-regarding entitlement feminism, and ceaselessly vaunt their independence, but the reality is, come the epidemic plague or foreign invasion, they’d become precisely the sort of useless baggage you’d trade for a box of shotgun shells or a jerry can of diesel."
Why didn't you do that?
White men as a group have high social and economic status, so a broad-spectrum put-down isn't likely to impact them very much. Women have spent a long time trying to overcome exclusionary social mores, and have correspondingly less social and economic capital, so it's in their interest to cooperate against overt sexists.
Do these homeless white men have high social and economic status? I'm curious to know when it is appropriate to generalize based on group membership, and when it is not.
EDIT: More curiosity from me: Has anyone demonstrated that any women were actually impacted by his statement (again, a few lines taken out of context from, well, a book-length book) in any real way?
The assumption seems to be that now he's irrevocably tainted as sexist, like some sort of charged particle inducing sexist discrimination on any nearby woman according to some inverse square law. I have yet to understand how a flippant (and joking) sentence or two in a book somehow causes anyone any real harm.

Now, if I've misunderstood something substantive about your argument I am open to correction. With regard to how I phrased your argument, the whole point was to make it clear why I don't find your argument convincing.
