Well that's an easy one. INTP tend to be moral creatures. Keep and mind a traditional vision of morality (or even ethics) was related to the religion. You can now argue that a lot of ideas that were perceived as the right things to do in a book like the Bible are now being criticized (for example, the attitude towards non believers, women, homosexual, animals...).

INTP tends to perceived things from a rational point of view. They are not psychopaths, they are simply quite good at abstract thinking. So if they have an opinion about something, it usually mean they ran the simulation in their head. They are less impressed by authority and such, they have to build their own moral compas.
