I fully understand what it is you are getting at but I think you should look at the history of your country in regards to this sort of thing. The US laws have progressively gone away from that rather than 'trickling' towards it, as you stated. Pre WWII the USA was very close in political standing to the Germans. This was followed by the McCarthy era of anti-communist hysteria where the rights of US citizens could be ignored at (virtual) governmental whim. Into the 60's & 70's where the rights & freedoms for so many things were fought for by the people, usually peacefully, & often opposed with force by the authorities. America of today is radically different(& better) than the America of 40+ years ago.
We all have to remain vigilant that things do not regress but never mistake the levels of rights & freedoms that you have..... and that many people of the past gave their time, energy, resources & sometimes lives for you to live in one of the freest countries in the world.
