I'm merely telling you what happens when people say "never again". If "rights" can be taken away from you (War on Drugs, Patriot Act, etc) then they aren't rights.
Yes, they are rights. Rights, as defined by the Founders, are that which require no participation by any other person other than his/her non interference. Among those, as written into the Declaration of Independence, are 'life, liberty, and the pursuit of happiness'. It was such rights of the people that inspired everything that is included in the Constitution of the United States. It is such rights that had been denied to them that the people took for themselves and resolved to never allow a government or individual to take away from them again.
You seem to think that because governments or individuals can infringe your rights, that the rights don't exist? You seem to think that because bad judgment is employed or mistakes are made that it negates any concept of rights?
If you have a dollar and somebody takes it away from you, does that mean you never had a dollar or that it doesn't exist?
