You absolutely should try and do something to stop it. My point is that the parent comment had an extremely rosy view of this country and how much it followed the constitution which was NOT true.
Just look at the abuses of J Edgar Hoover with the FBI to see that warrant-less wiretaps did occur and were used to abuse specific people. Sure it was not on the scale we have not but that is a difference in scale not in kind.
One of the biggest problems I see is actually with citzens united ruling. In my state many people worked for a long time to get laws changed regarding campaign finance, state budget etc and with a single ruling the supreme court wiped that out. In the very next election almost all the officials were pro fracking since those companies outspent everyone else by a landside. How do you really get good people in office that do what the voters want when elections are almost purely defined by money and under citizen's united corporations can spend unlimited funds on elections?
My city even voted to start its own renewable power system for a lot of reasons. The local power company is spending more than my city is worth to fight it. They managed to spend enough money to get a new ballot issue put on that would basically stop the process and most people polled that signed that ballot measure thought it was to help the city create its own utility not destroy it. They did not even realize that the current power company was behind it. How do you really fight against corporations on that scale? If you can't fight those corporations how can you get any change in the government?
I try to view the world as it is not as what I want it to be. Only through seeing what is out there and accepting the way the world is can you figure out how to change it. In the 70s the dirty laundry was better kept away from the public but this country still did not follow the constitution and value freedom, it only claimed to.
