The victim principle and common sense just as religion is supposed to do, but both sometimes fail to achieve their purpose.
Addtionally. I have to disagree with you on "changing belief to fit the wind and situations". Religions seem to do that all the time.
Agreed on religion doing that but there are also religious ppl who dont change their beliefs. Just ask our atheist friends here on the board. Im sure they would be more than happy to regail us with their views of "ignorant, non thinking, moronic religious ppl"
By citing the victim principle you assume that we all have the same base of morality. Its common sense to do what you have to do to survive as well. That will put you at odds with the victim principle from time to time.
and its then when ppl will change their views to suit their current situation. They will rationalize their actions b/c its human nature to do so, even if those actions fly in the face of their held beliefs.
The difference is that with religion you have a certain set of guidelines that says this is right and this is wrong.
The victim principle and common sense look different depending on what side of the situation you are on.
