Philosophy X (could be political, religious, whatever) says its adherents should do a, b, and c good deeds, but most of the adherents to philosophy X follow a distorted version of the philosophy that leads them to do x, y, and z bad things. OR most of the adherents of philosophy X do a, b, and c good things, but there's a high correlation between adhering to philosophy X and also doing x, y, and z bad things. We want to get people to stop doing x, y, and z.
So do we try to get rid of philosophy X itself? Or do we try to get people to see the ideal (true) version of philosophy X and respond accordingly?
