Wait, do they actually fear that Dylann Storm Roof’s admitted racist attack IS going to spark a Race War? Are they afraid that if they do admit it was racism, that all the black people really will be fixing to chop up the Wingnut Media and One Percentiles into little itsy pieces? It is almost like they are admitting their own complicity, that NOT tamping down the racist angle at this point is a worse gamble than just ignoring the reality and suffering the consequences.
A large swath of the US population honestyly can no longer distinguish normal from nuts and evil from good anymore. They are called wingnuts, libertarians, and religious conservatives.
