Europe probably is more diverse in languages and accents, but if someone from the U.S. north goes to the south (or vice versa), they have a hard time understanding what anyone is saying!
Some Americans are really easy to relate with while others are completely impossible to figure out. Its just that I dont agree with anything they say where as other Americans are so easy to get along with. The same type of humour but some people. Good god. Weirdos. In that sense US is diverse.
I dont like the current US politics though and I hope they snap out of it soon.
US got good music, movie, entertainment culture.
