U.S. Citizens Giving up Civil Liberties

I do not think that U.S citizens should be forced to give up their civil liberties during a time of war.  We worked so hard to get these liberties and we should not have to give them up.  This goes against liberties such as the freedom of speech.  I think it would be alright if people made suggestions to give up their civil liberties during a time of war but they should not be forced to.  The citizens should be able to do what they feel is right.  I don't think the government should have to enforce loyalty either.  I think the government could tell the citizens what is going on and if the people wanted to help support the people in the war then they can.  But, if the citizens do not want to help them then they should not be forced to by the government.
