Tokio Hotel's Bill Kaulitz: classmates pulled down his trousers to 'determine' his gender

Bill Kaulitz, 36-year-old frontman of Tokio Hotel, has revealed in a candid interview that he suffered violent, hate-motivated attacks in his youth due to his androgynous appearance. Peers would pull down his trousers and grab him between the legs, claiming they wanted to "determine" his gender. The musician is now publicly confronting that painful chapter of his past.
