Data collection. One of the reasons the Nazis were so successful was because countries like Germany and the Netherlands kept excellent records on people. As soon as they got access to those records, they were easily able to identify people as undesirables and send them off to the camps.
Today, Google collects data like this on you, and then the US government buys it off them, bypassing constitutional privacy protections. This is the one of the ways ICE is targeting people. (Feel free to replace with your local equivalent.)
In order to prevent things like this happening, we should prohibit the collection of the data in the first place.
