For further context the phrase was largely leveraged to stop the spread of bad news on the war front. They were fairly confident that a German spy network didn't exist within American society at the time of the campaign, but didn't want negative press to circulate about the war effort.

I'm not saying it wasn't a good policy and a catchy phrase (propaganda isn't automatically evil), I'm saying we're not in WWII (and hopefully not in the sequel either.)

Back then was not the time for civil disobedience, but a lot of men and women fought and gave their lives for us to be able to do it when it is suitable.

Which it now is. With piracy and weed, for instance.
