Should civil rights be promised to american citizens during a time of war?

I think americans should have limited rights during a time of war. Essential rights like the freedom of speech how ever should still be promised to american citizens. We as a country have always had pride in being a democracy, and forcing americans to think a certain way is more like communism rather than a democratic republic. And we as a country are 100% against communism. We fought wars after WWI to stop the spread of communism. So why on earth would we force people to think a certain way if that totally goes against our moral fibers? it just doesnt make sense.
