You are confusing "injustice" with "lack of democracy". There is a distinct difference between the two. A "just" system can exist in an absolute dictatorship provided the dictator is a fair and honest person while injustice can prevail at all levels of society within a perfectly democratic system as govt policies of the time simply reflect the will of the electorate which put them in office.
The Japs Americans were interned too. However, the same would never happen today. That's how democracies progress.. the govt has to be in sync with society and not the other way round as is the case in sinkiepoor.
The 2000 election was controversial because the ballot box did not have the required precision to separate two evenly matched candidates. There was no photo finish software to help the judges make a call.
However, the Americans had another chance to get rid of Bush in 2004 and he won that election fair and square.
America has one of the best systems on the world. The two term limit was a stroke of genius by the founding fathers. It makes sure that the US can never become a LEEapore.
