well if you are respectful an kind listening to what their feelings are and trying to understand things from their point of view and it may change their view of one American with tattoos! You will most likely be provoked if you start to talk about Politics or religion I would avoid these subjectsc
I'm sure they don't really hate ordinary American People. But if they're the kind of people that really hate a whole nationality, I wouldn't waste my time trying to win them over. Life's too short to deal with assholes.
Brace yourself! I am still easily swayed by my parents' opinions. If you live in America and are going over there for a visit they expect you to bring gifts "gostintsy"
