Honestly sometimes it's a result of the veil thingy. Sometimes a person can come to Satanism and still be effected by this. It may prevent them from really doing much or advancing sometimes. It does not matter what you say or do around someone effected by this they won't listen. The only option is to wait or try to get them to do the rtrs more or take the time to break this down yourself on this person it may be hard with some people if they are willingly connected to something bad like xtianity and obvious to this in that case you may have to disconnect them from this with workings if they won't do it themselves.
If you do this with an SS your actually really helping them a lot. They will probably thank you once they realize what you did and they will if you do it right.
