The US isn't China or Europe or Australia or Britain. We have our own unique culture. It has pluses and minuses like any other distinct culture does.
Yep it does. The some of the plusses are green chile, driving 20,000 miles on the emergency spare and paper license plates (screw you other 49 states), and one big minuses is the rather large number of people getting killed by guns (from what I recall, the majority are accidents and suicide, but I may be mistaken).
It requires a certain perspective to understand and appreciate other cultures. Perhaps you may develop that perspective someday.
It also requires a certain perspective to see the bad things about your culture, which are hard to get from the inside. Either way though lots of people getting killed is pretty much not a good thing.
