The Christian fellowship/pseudo-church I was with up in Rawlins Wyoming did stuff like that. But it was not racial by any means. We read verses, we'd write our sins down on paper, light the cross, then sing a few songs of repentance and forgiveness, and finally throw the wadded up sins into the fire and sing more songs. There was never anything racist there. The racist view of lighting the cross was from the movie "The Birth of a Nation" (1915). They also distorted the original history of the Ku Klux Klan. The original lighting of the cross is to rid us of the demons by casting them and or sins into into the light of our Lord and Savior. It had been a long time, so may I get something wrong here. But no, a true lighting of the cross is not racist.
