SA still doesn't have a vision on the afterlife, as far as I know, which would be the number one concern of any religious person.
http://wiki.battlemaster.org/wiki/Sanguis_Astroism/Writings#On_the_AfterlifeAll it has is vague theology that doesn't really force anyone to do anything they wouldn't like to do.
Of all the religions I have ever been in, it's the only one which has a sense of "if x, you should do y". Granted, it's a little script with three stars that rotate, it's not much, but it's more than anything else.
All can basically "worship" the stars in whatever way they wish.
Good luck with that. You really have no idea what you are talking about.
