Of course the angry ballbuster cunts hate 40-year-old bachelors, as they represent the inmates that escaped their jail. A bachelor in his 40's ( non-incel) is a free-thinker who won't be suckered into an investment that offers only diminishing returns. He may want to marry, he may not; he may want children, he may not. But what a 40-something bachelor most assuredly DOESN'T want is a 40-something woman. This truism infuriates them, as it means they are basically invisible to the world. 

Now a 40-something spinsters is most assuredly damaged goods. Women are programmed to preg, and one that doesn't must have a screw-loose. This - aside from their past-expiration physical looks - is why no man in his right mind would bother with one. After all, why would he when almost all late 20-something women will happily marry a 40+ year old man if he has his shit together?
