Certain critics, such as Jussi Lahtonen of the Finnish indie rock magazine "Sue", have argued that separating Christian from non-Christian black metal artists "feels rather pointless". However, early groups such as Horde and Antestor refused to call their music "black metal" because they felt that the style was strongly associated with Satanism. Horde called its music "holy unblack metal", and Antestor preferred to call their music "sorrow metal" instead. Stefan Rydehed, director of the metal documentary "Light in Darkness – Nemesis Divina" says about the unblack metal musicians based on his interviews: "The Christian black metal musicians see themselves as a part of the black metal community but they have a hard time to be accepted. Not only from other black metal musicians but also the society and ordinary Christians."
