Here are some of the piece's highlights.
it's potentially plausible that we can assume Holden not only was bisexual, but that he didn't even know it yet and that that was obviously one of the reasons he felt so alone, so different,
Behind the disapproval of societal norms which included as well the selfish, bourgeois American exceptionalist values, was a young man who did not have adult models with whom he could align.
Why wouldn't Holden's possible bisexuality contribute to his feelings of isolation and alienation? Especially since studies have shown that sexually frustrated individuals struggle with anxiety, isolation and alienation?
