The shooter in Parkland was psychologically disturbed, the product of an unusual family background. He was adopted at age 2 by a middle-aged couple. His adoptive father died when he was 5, and his mother died last year. The shooter was diagnosed with depression, autism, and attention deficit hyperactivity disorder. To make such an obviously damaged person — who was recognized by school officials and his fellow students as having profound personal problems — symbolic of an allegedly pervasive “crisis in masculinity” is not a logical inference.
