It’s easy to think clear lies is something easy to define, but it’s not. Once you make any kind of speech illegal, you run the risk of slippery sloping it and making opinion illegal.
Can you imagine if it was left up to this administration to define what “clear lies” were? You wouldn’t like that, I hope.
Free speech is important: protect it.
Edit: and to those mentioning Fairness doctrine:
The fairness doctrine of the United States Federal Communications Commission (FCC), introduced in 1949, was a policy that required the holders of broadcast licenses both to present controversial issues of public importance and to do so in a manner that was—in the FCC’s view—honest, equitable, and balanced.
The FCC. Which is currently headed by Ajit Pai, the sellout who got rid of Net Neutrality. After seeing how that turned out, you are still going to trust the government to regulate it honestly, with the best interests of the people in mind?
