Black Flag's change in musical style and appearance alienated many of their original fans, who focused their displeasure on Rollins by punching him in the mouth, stabbing him with pens, or scratching him with their nails, among other things. He often fought back, dragging audience members on stage and assaulting them. During a Black Flag concert, Rollins repeatedly punched a fan in the face who had continuously reached for his microphone. Rollins became increasingly alienated from the audience; in his tour diary, Rollins wrote "When they spit at me, when they grab at me, they aren't hurting me. When I push out and mangle the flesh of another, it's falling so short of what I really want to do to them." During the Unicorn legal dispute, Rollins had started a weight-lifting program, and by their 1984 tours, he had become visibly well-built; journalist Michael Azerrad later commented that "his powerful physique was a metaphor for the impregnable emotional shield he was developing around himself." Rollins has since replied that "no, the training was just basically a way to push myself."
