The New York Post is under fire for its “shameful” front-page attack on Brooklyn rapper Ka, who’s also a fire captain in the NYFD. In the article, published yesterday, the Post says Ka (real name Kaseem Ryan) writes songs “peppered with the N-word, drugs, violence and anti-cop lyrics ... [that] describe ghetto life, a world of guns, dope and despair.” Although Ryan had not kept his rap career completely quiet—in a 2013 interview with Noisey, he said some coworkers “respect what I do”—the Post tracked down fellow firefighters who were unfamiliar with his music. One response: “As a New York City firefighter, he should be trying to bring people together rather than fracture relationships, especially in communities of color.” Fans rallied behind Ka, as Fact points out, but he’s yet to explicitly address the situation. El-P also chimed in. See some responses below. Update (1:33 p.m.): Killer Mike has weighed in, too, via a lengthy Instagram post. Find that below, too.

Ka recently released Honor Killed the Samurai. Its predecessor, The Night’s Gambit, received an honorable mention in Pitchfork’s Albums of 2013.
