In my opinion the article speaks solely about trophy hunting/sport hunting:

In the groundbreaking 1948 book, Abnormal Psychology and Modern Life, which remains the most authoritative survey of abnormal psychology (renowned for its comprehensiveness, balance of theory and practice, strong research base, clinical sensitivity, and which is also updated annually), the authors state:

“Perhaps more directly relevant are experiences in which individual infliction of pain on an animal or another person has given rise to sexual excitement. We have noted elsewhere the connection between strong emotional and sexual stimulation.”

Menninger’s theory was later expanded by other leaders in the field of psychology, including Dr. Joel R. Saper (University of Michigan) who theorizes that hunting “may reflect a profound yet subtle psychosexual inadequacy.” While clinical psychologist Margaret Brooke-Williams adds, “Hunters are seeking reassurance of their sexuality. The feeling of power that hunting brings temporarily relieves this sexual uneasiness.”
