We must give more powers to the FBI to remove misinformation. Not only on Twitter, but in schools, grocery stores, and kindergartens. Just hammer the truth through their thick skulls 24/7.
Combating misinformation is an important issue, any efforts to do so must be balanced with considerations of free speech, government power, and practicality.
It may be more effective to focus on promoting accurate information and critical thinking rather than trying to force people to accept the "truth."
