This is a tough nut cookie to crack and subversive. You are trying to open up to something new, but then your subconscious picks up on some pattern and triggers your defenses. For example, you may want to partake in a healing ritual, but then you recognize that there is a shaman and that the whole thing is demonic and evil, which closes you up to it.
Ironically, to protect someone from indoctrination, you have to make him aware of the ways in which he will be indoctrinated. But that is indoctrination in and of itself and ultimately only a safeguard for loyalty to possible bullshit.
Those weed smoking hippies are brainless and no good.
Those occult witchmasters will steal your soul.
Those conspiracy theorists are all morons who just want to see what is not there.
You learn these ideas in a friendly environment that you trust.
Another one: Men are evil, vile and selfish. The assholes will try to take you away from my safe and good teachings and that will be your downfall.
In principle, you describe human behavior typical for a belief group and then shame it or associate it with fear. If these successfully predict a pattern of behavior that would naturally challenge your beliefs, the safeguard knocks in.
Call the lion a lion to shame it. Oh, you are just being a lion here, shame on you!
