The problem with censoring "misinformation" is, who determines what is misinformation?
Is it anything that goes against the mainstream accepted view?
Is it anything that contradicts a certain narrative?
Is it something that someone may find offensive?
Is it anything that comes from a person whose view and beliefs don't align with yours?
If any of these prevailed in the past, mankind would have missed out on some amazing discoveries and achievements.
The world was once convinced and science had a consensus that the world was flat and the sun revolved around the earth.
Medical science once believed that drinking mercury and leeching was beneficial.
Scientists criticized Louis Pasteur when he said bacteria can cause diseases.
The mainstream once accepted the view that slavery was tolerable and necessary.
There was once a scientific consensus that there would be a worldwide ice age by the 20th century.
Experts once told us that we would run out of oil by 1990.
Scientists once believed the Earth’s continents were stable and did not move till Alfred Wegener’s formulation of the continental drift theory, and later and more properly the elucidation of plate tectonics during the 1950s and 1960s.
For years, doctors told us ulcers were caused by stress till Barry Marshal discovered that the bacterium H. pylori caused peptic ulcer disease, leading him to win a Nobel Prize in 2005.
This is why we should never censor ideas or speech even if you don't like it or disagree with it.
