This lesson doesn't make sense in a two-party system where the two parties have wildly different levels of trustworthiness.
The left suppressing lies only opens the door to the right suppressing the truth, because the right was an enemy of truth and a spreader of lies from the beginning. The answer can't be "allow the lies so the truth has a chance to survive", that's just a compromise that brings us further from the truth.
Demanding neutrality on truthfulness in mass communication, especially during extreme political turbulence, is a terrible idea.
