Thank you for a detailed and insightful comment, Claire. I sincerely hope you'll write an article on this topic. I bet it would generate a lot of interest.
Another commenter already called me out for my ignorance of the reproductive realities of generations past. I read a lot of history and anthropology, but I guess I get too much of my world view from fiction.
The incels don't want to hear about lonely women, as that news spoils their myth of females controlling all things sexual. So they devalue the ones who might actually be willing to give them a chance. Like Groucho Marx said, "I would never join a club that would accept me as a member."
