I know this is the logic the Twitter police use to chase people from jobs, but its certainly not true. Mill argued free speech should be protected in all cases for two great reasons. The first being that one never really knows if something is right or wrong. Many scientific have turned out correct that were disallowed initially. Secondly, even if a view is wrong it acts as a foil to the correct view. People learn a greater appreciation for the truth by seeing the bad examples. This acts as natural selection for ideas.
