Tails – theamnesicincognitolivesystem
From the about page:
Tails is a live system that aims to preserve your privacy and anonymity. It helps you to use the Internet anonymously and circumvent censorship almost anywhere you go and on any computer but leaving no trace unless you ask it to explicitly.
Whatever your prediction for the US 2016 presidential election, Hairy Thunderer or Cosmic Muffin, you are going to need Tails
For free speech and/or privacy in 2017, get Tails.
It really is that simple.
