How much tribalism do you think there is in American politics? Meaning, how much do you think people change their opinions to match whatever they think they "should" believe, based on what their party/church/community/family/friends believe?
It seems to me that this is how most people form virtually ALL of their political views, rather than thinking for themselves. It seems very strange that the people who oppose bellicose foreign policy are almost invariably the same people who support abortion, oppose major changes to education and social security, favor gay marriage, tolerate higher taxes (especially on the rich), and oppose guns. Likewise for people with the opposite views. As far as I can tell, there are no common philosophical threads running through all of these views, nor even any practical worldview that would lead a certain type of person to inherently agree with them all.
This leads me to the conclusion that most people really don't put any thought into their views...they simply convince themselves that they believe which ever view they feel that someone like them is "supposed" to hold. And I think this tribalism in our politics is particularly strong among people who follow politics closely. What do you think?
