Bergler has been criticized because he believed that homosexuality was caused by psychological issues. In his defense, his views on this subject were framed by the rigid attitudes of his era. His writings on the subject constituted about 10 percent of his total output. It would surely be unwise to discredit his whole body of work on the basis of these erroneous views.
Bergler was aware of the enormous resistance to his ideas and understood that we are determined emotionally, through our defenses, not to disturb the psychic status quo. He wrote once that his books were time-bombs that would go off in 100 years. Perhaps now, faced with impending calamity, we have become open-minded enough to take a second look at his ideas.
