And I wasn't talking about patriotism for all of humanity, but love and compassion. I'm not sure why you are still talking about that.
If you've never been to China or attempted to form communal ties there, then of course you'll prefer the community you're in now. My point was that nationalism and patriotism are predicated upon artificial boundaries and the emphasis on what is different between societies. You assert that local level patriotism is better... but that is just another border, except it is more on a local level. This town, this county, this population. Before nationalism, even counties had conflicts based on their borders. Even now, there are regional rivalries within nations.
It's this divisionalism that doesn't make sense to me, because I have been to a number of places and see humans in a different light I suppose. Whether it's local or national, it makes no difference to me. It's still a division.
