Regardless of where we are, if we see or experience something unacceptable by us, we as human beings will complain. Of course it makes more logical sense to present our issues to a person of authority and power who can actually help us, but its still very therapeutic to discuss it with like-minded and/or sympathetic people as well.
I don't know about anyone else but even when I was back in my country of birth if I didn't like something I'm not gonna shut up about it! Similarly as much as I love living here, far more than I have loved living anywhere else, if I see or go through negative things then I will express my feelings. Doesn't mean I'd rather be anywhere else though as I know by now no country is perfect!
