Haha! Well it definitely is an effect out there. I don't know whether that effect is stronger or weaker than it used to be, or how many of the cases of women being gay are caused by an impression of the available men less desirable than what they would prefer. I would guess it has gone up. Also low expectations of men from father figures or lack thereof.

I strongly lean to the last sentence. Would like to see a newer data then e. g. Sowell presented.
Ooh, I haven't yet come across anything from Sowell on gay statistics and sociological considerations, would be fascinating to see. I really like his work on family culture and welfare handouts and whatnot. And the epistemology and metaphilosophy of the Vision of the Anointed vs the Tragic Vision laid out in his Vision of the Anointed book, beautiful, essential reading, that!
I know women who have a genuine, long lasting tendency toward being attracted to other women, who have also been influenced in their perceptions and attractions by the sorts of men they are around and their expectations for what men are likely to provide in a relationship, in both directions. Bad experiences of men in their lives can leave a woman with unusually low expectations for men and may signal them to just lean into a preexisting natural attraction to other women if they have one. Good experiences can leave them realizing there is at least one, realistic, opportunity for them to be with a strong, principled man, and might awaken some dormant hetero leanings.
Girls are frequently bi or bi-leaning. I think it's part of the natural process of evolutionary pressures being very selective about which men get to procreate. It may or may not have been something that helped polygamous relationships in the past to be stable too, like harems and shit. Idk. That's my thoughts from an evolutionary pressure point of view.
