We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
A lot of gobblygook . I couldn't identify with any of it. Too old I guess and I don't drink and do drugs. But I don't think this is really what the author believe it is. My theory is that most every "marriageable" woman is married by 21. The rest by choice or DNA are not. What the author is doing is looking at the less attractive, unfeminine, Sexually unapproachable or too approachable, gay, uninterested and terrible personalities. From this leftover group he is making a calculation about all women.
You are correct. The brightest and best-looking girls attract a lot of suitors. So they get married early. But there is also another factor at work: Politics. So many girls nowadays want to express their political views; they don't realize how ugly this makes them. They prioritize all sorts of irrelevant things, like asserting their independence, focusing on a career, globalism, and even loving their cat as if it were a person. These girls aren't going to change, they are committed to the political process, and they will spend the rest of their lives wearing a pussy hat. So now we've got an epidemic of horrible little communist tramps, who will do anything to make sure that people don't fall in love. That's not what they want.
