In leftist spaces, right-leaning ideas are challenged. In right-leaning spaces, leftists are banned and leftist ideas are censored. Why are conservatives opposed to the free marketplace of ideas?
Serious question.
Conservatives know in their hearts that they are a fringe minority when it comes to views on how to treat others.
Colbert was right reality has a liberal bias and conservatives need a safe space to pretend that the numbers are equal and that their arguments have validity.
Often times you notice conservative threads that are locked contain misinformation and outright lies. For instance they call the Russia investigation a hoax.
If reality pierces that bubble they are shown for the fools they are so they have to pretend that liberals are brigading in bad faith and not simply showing conservative views are simply invalid factually.
