Actually, you are very wrong. It was not just minorities Hitler and the Gestapo went after, but anyone who disagreed with their policies. Heck, you could write poetry criticizing the Nazi government, and they would consider you as going against their policies, and be taken in, and never seen again!
Do you know how many people were rounded up into concentration camps, all because they disagreed and opposed Nazi policies?
The comparison fails if trying to say our government is like Hitler especially if the claim is the government wants to go after everyone. If the comparison is to try and control everyone just for the sake of control, that is not what Hitler did, that is also not what our government is doing.
They controlled the people through FEAR, which is exactly what our government is doing now. Monitering our Youtube, Yahoo, Google accounts, our emails, and phone conversations, is literally Gestapo fear tactics. That is what controlled the German population at large, so they were too scared and afraid to fight back. So many Germans hated Nazi policies, but were too afraid for their families and themselves to stand up. This is exactly what our government, through the NSA is doing.
I wouldn't call it "sensibility" to let the government do my thinking for me....
