The dismissal of the culture thing is incorrect.
Although the US has produced some bad TV etc I don't think you can say that The Wire, The Sopranos, Breaking Bad, GOT etc etc etc are trash. Yu say you rarely watch TV but felt free to comment? What informs your position?
Music: Rock and Roll, blues, jazz, R and B, disco, punk, ( yes the ramones is the first punk record) funk, hip hop etc all began in the states.
Jackson Pollock, Andy Warhol etc etc
Movies, I'm not even going to list all the great American movies.
"They are not the heart of global civilised culture and it's quite sad that you think this. This type of statement is precisely what alienates people towards Americans"
Again you say that you don't watch American movies, but felt the need to make a statement that was blatantly inaccurate, and shows your own lack of knowledge, understanding and culture.
Journalism? The US has had some great examples of high quality journalism. Woodward and Bernstein anyone?
Displaying ignorance whilst trying to be pretentious is exactly why your post is a load of rubbish.
