If you look at it from afar, you'll find both sides do it for the LOVE of Dhan Guru Gobind Singh Nirankaar Ji! - Those for it, say it's his and the reasons for it being very explicit, sexual etc etc - Those who are against it, are so because they say there is not way Dhan Guru Gobind Singh Nirankaar Ji! can write such things, or can be associated with him. SO it's all out of love, at the end of the day SGGS is GURU and that's all that matters. It has authority over ALL other Granths authentic or otherwise :)
