I heard pretty nasty things about how Asians are treated in the U.S
Then you've been talking to idiots. They either can't separate isolated incidents from general behavior or they are basing their entire view of a country on the equivalent of a high school atmosphere. I've seen tons of anti-American bullshit on the internet from Russians, but I found Russia to be a great place. Just something to think about...
By asking such stupid questions and being so gullible, you are perpetuating a stereotype - one that would piss me off just as much as if it was about any other country. Go read an American news site if you want to see what's going on. If Asians were really treated so poorly, it would be in the news.
You will find idiots who make racist remarks in every city no matter where you are on the entire planet. Believing that an entire country behaves the same way makes you an even bigger idiot. I grew up in the south and witnessed very, very few incidents that could be considered racist - all of which were dealt with swiftly. It's not different there than it is anywhere else in the country. The only exception might be very rural areas with older people who haven't let go of the past, but they are a dying breed.
Nobody cares about Asians. The Chinese students that were living in my dorm were told the same BS when they were in China. Its not true, overt racism is pretty uncommon anymore in most places.
