Yes, I am a "westerner", though I also have a deep appreciation for eastern culture. I'll refer you to my introductory post if you want to learn more about me and who I am. 😉
To piggyback on your train of thought, even eastern culture has its ultimate origin in Africa, where our species first evolved and developed the social structures, instincts and behaviors that typify humankind. It's all about how far back you are willing to go.
