It is odd but 'balance' is always a state off transition, not a permanent destination.  

If you have no choice to stop cultural change - and we don't, then we'll always have segments of the culture that are out of sync or, as you put in contradiction.

It good that our nation has a tension that we can discuss without mass violence.  We have people who hold their traditions and/ or values regardless of modern culture.  Others want change because of what they may believe is a cultural injustice.  Then you have those with infinite curiosity who love the challenge of complexity that changes our human knowledge base.

Anywho, the world far more cultural subgroups than it has nation/states.   We have no choice but to find civil ways to handle diversity.  Physical walls make no difference in keeping out exposure to other cultures 

We live in an interesting moment.
