Seriously, dont take Youtube comments seriously.
I do have to say that pretty much everything that I see or hear of America shows stupid people doing stupid ignorant/arrogant things. Dont worry, I know this doesnt apply to a lot of people, but I am sure that it also does apply to a lot of other people.
I still dont know HOW much the way your country is presented to everyone else is an exaggeration, i'd have to find out by actually visiting the country and all its states myself.
We all put up with stereotypes I guess. The english have to hear about how they are posh and uppity all the time, and for some strange reason (because this sort of implies the complete opposite) also that its just a hooligan country.
The japanese, the chinese, and everyone else.
Us germans, well I dont think I even need to say anything...
