I am not sure you are serious.
The USA has always had a group of people to oppress. Our plight hardly compares to what the Native American tribes had to endure, or the slaves of the pre-civil war era. Even the African Americans of the post civil war era to civil rights era can show evidence of much harsher treatment than what we are going through. We can compare ourselves to that when men in white sheets come knocking on our doors at night.
America is actually doing better now in this area concerning civil rights, but it is still inexcusable, especially in this modern time, that registry laws are being used on a whole class of people. Have we learned nothing from history?
