what do you mean "my" country? you're just a guy who lives on earth, thats what we all are! you should not feel guilt for what some sadistic monarchy decided for you! part of the reason we are all fucked is because this subtle nationalism still exists!
a huge part of the problem is the "my country" did this and "your country" did that, instead it should be "we did this" we are just one species on a floating rock, nothing more!
we will never, ever fix societies problems with nationalism still being prevalant, a huge shift in the norm is required currently.
