Allegations against R. Kelly have finally exploded into the #MeToo era with Lifetime’s “Surviving R. Kelly.” But the singer’s troubling behavior can be traced back decades. “There was a lot of sexual energy around Kelly that we as young people felt was a little bit dark and a little bit inappropriate and a little bit taboo,” says Jeffrey Q. McCune Jr., who studies race, gender and popular culture at Washington University in St. Louis. In the early 1990s, McCune was a student at Kenwood Academy, the Chicago magnet school Kelly had attended just a few years before — and a classmate to one of Kelly’s earliest accusers.
