>>483958If I had to guess from my perspective maybe it has to do with many families especially in the more liberal parts of the US have been utterly destroyed and boys are more likely to live with their mother only and be depressed.
Single Mother households lead to femininity, aswell as a myriad of psychological issues, aswell as not knowing basic things a proper father would be able to teach you.
Depression can lead to escapism and depending on your circumstances and what has happened in your life like perhaps living in a place with a really broken sexual market if you're an average dude might lead to sociopathy aswell as escapism.
This somehow all combined might lead to incest fetishes? Just some speculation but not sure.
