I've been living abroad in various places for a few years now, and I feel like if someone were to vandalise the flag of my home country in an act of protest I don't think it would trigger much of an emotional response in me at all. No more, probably, than someone vandalising the flag of my sports team (that's to say, not much).
I wonder where this emotional attachment to tribal symbols starts and ends. I haven't done much at all in my life (voted a few times, otherwise just lived within the system) to create my home nation. It's just the part of the world where I happened to be born.
Even if I had fought hard to change my country and later become proud of what it had become, I would question whether someone defacing a symbol of that country would trigger an emotional response.
Am I alone in this? Is this tribalism something which is usually considered innate or learned / forgotten?
