America hasn't done anything to me to deserve any kind of strong feelings against it. But that is obviously personal, like any other world power in history, it would have a lot of people who have very strong feelings about it.
For now, it does not interfere with my life too much, so I can maintain my neutrality. But things change, who knows what will happen in 10 years.
Ultimately you need to take patriotism with a giant block of salt.
