There is always a little truth in most things. The majority of people first decide what the want to believe and then they go about working to prove what they just decided. A good example is that 90% + follow a certain religion because they were raised that way by their parents. THey then spend the rest of their life proving to themselves they are right in the belief their parent have taught them. Few actually spend a life time trying to determine what they believe is right and then follow that belief even if it is different.. Some become damaged by the belief that was passed to them and they either become non believers or go to other routes.
Some of this "religion" belief can also be translated to beliefs in socialism, democracy, etc.etc. Your parent was a Demoncrat so you are a Democrat and will go to extreme limits to prove why you have the "true answer".
Kind of basic stuff.
