I don't think so. It takes both. Those cult compounds I mentioned - the ones that get really bad are likely that way because no one in the compound feels they have the authority to question the others. It is important to feel that your concerns are valid or being heard, and important to try and make them be heard if it is important to you. Perhaps there are others who feel the same way, but how will you ever know unless you speak your mind and take that step to receive feedback from those others? Maybe you are strongly in the minority, and your ideas get shut down.
For example - let's say one among the group is racist, and doesn't feel that any black people belong in the group. When they voice their opinion, and try out the waters, perhaps everyone tells them that it is a nasty opinion or idea to be having, and they learn that their opinion isn't going to fly as the ruling idea over the group. It is in that moment that they should then begin some self-reflection to figure out why it is they feel that way, and whether or not it is "right" in the greater scope.
If, however, someone notices that kids in the group are being treated unfairly - that the adults who do work are given some form of compensation, for example, and the kids are put to work just as often, but are given no compensation, then perhaps if they voice their opinion on this matter there will be others who agree with them, and perhaps those of the group who believe the kids are being treated unfairly can sway the others over to their line of thinking, get a majority, and get things changed.
Ultimately, others choices and actions simply must be questioned. They must - in all avenues of activity. Religion does not get a "free pass" from this "just because." I get that it is a sensitive subject for many, and very likely because they have very little substantiation and it becomes extremely uncomfortable to try and defend something for which you have no solid basis to begin with. I understand it... I just don't care.
