Core to the Right

My recent encounters with international relations and vandalism have me wondering how incompatible cultures really are. I consider myself to be a cross-cultural being, a sentient example of contamination, if you will. If I had never been exposed to one of the two dominant cultures in my life, would I still have made the choices that I have recently made? Am I driven by culture or personality? I am personally of the opinion that the two share a dialectic relationship, but there is a distinct possibility that one may dominate that other. What is the influential ratio of culture to personality with respect to individual behaviour?
