FORT LAUDERDALE, Fla. — The polarizing survivor of the Parkland mass shooting has been falsely labeled a crisis actor, vilified by the NRA and called names by TV hosts. And David Hogg isn’t avoiding self-criticism in his new book. In fact, he calls himself “arrogant,” ”skinny” and details his rejection by girls.

Eighteen-year-old Hogg admits he was super cocky after being named debate captain at Marjory Stoneman Douglas High School.

“I was just so narcissistic and pretentious back then, even more than I am now … Pretentiousness was probably my substitute for actual confidence,” Hogg writes in “#NeverAgain,” which he co-authored with his sister Lauren Hogg. Released this month, it’s published by Random House. The siblings are donating the proceeds to charity.

The teen talks about how he felt like an “outsider” when he first moved to the upscale Florida community halfway through the school year in 2014, but found a sense of place through journalism and photography.

In an interview in New York on Tuesday, Hogg told a video journalist from The Associated Press that it was important for him to be vulnerable in the book and take inventory of his own shortcomings.

“I think America also needs to face its own problems as well. And I hope the book kind of teaches empathy for everybody,” he said.
