We are, and have almost always been a "bastion of civil rights". Even during slavery we had a republic and rule of law, even if not everyone was included. Even this was better than anywhere else in the world at the time. We may not be perfect, but we at least try to be the good guys. As wrong as almost all of those things you mention are (the internment of Japanese, German and Italian Americans was a justified and necessary security measure at a time when we faced a possible fifth-column threat from these groups. Seizing their property without compensation was not justified however...) well over 50 years into our past.
