Violations of Civil Rights that weren't fought for? What events in American history would be considered violations of TODAY's civil rights?

OK, this is for a history final and i need help thinking events in history when the Civil Rights of the people were violated and were not fought for. Think of the civil rights we have today. We didn’t always have them. Because of that, people’s rights were violated a lot in the past. We have the obvious examples, like slavery or restriction of voting rights for women. What I’m asking is if there are any violations of human/civil rights that were overlooked or not really talked about. I’m looking specifically for cases where people COULD’VE fought for their rights, but they didn’t.
