Is it right idf the government can take away rights in a time of war?

I think it was uncostitutional when the government made the people of the U.S. give up certain freedoms during WWI. When the government was basically filtering everything said negativly about the war effort was not allowed to posted. Which goes against the admendment to freedom of speech and press. It was wrong and a dark time in the American times. It was unconstituntional.
