There are many things to think about in this world, and many things to do.
I myself don't really care much for reincarnation.
I agree that Satanist have largely similar thinking methods and philosophies.
However, we are individuals, so therefore, with due respect I don't think you should generalize on what Satanists ponder about, and what things we are interested in.
Obviously, some people here do seem to be interested or amused, by the notion of reincarnation, just as many here are interested in magick, Norse mythology, other cultures, et cetera.
really, what i was trying to get across, is that reincarnation isn't something that a satanist believes in. perhaps my wording was a little goofy. but you are right, there is a difference between belief and interest, yes.
