Civil liberties during wartime

I think that Americans should not be to give up their civil liberties. This is a violation of the first amendment, freedom of speech. We should be able to voice any opinions about the government. We live in America, the land of the free. The government shouldn't need to enforce loyalty because even though someone disagrees on some policy or action of the goverment, most likely they are still loyal to them. I feel that censorship and giving up civil liberties goes against all principles that our nation was founded on. It is a very undemocratic act and should not be justifiable to do.
