It's called cognitive dissonance. The dissonance is an uncomfortable feeling to the person suffering it. Therefore the person must either change their behavior, their attitude, their belief and/or lash out at the person/idea causing it in order to restore mental balance.
The fake media are too invested in their beliefs. They are "true believers". Their attitudes are set. They can't be changed. Their behavior can't change because they will be shunned by their group. So the only option left is to censor the idea/person or destroy the idea/person.
If they should allow the idea/person to continue and do not change their behavior, attitude or beliefs, they will be stricken literally "insane" & unable to function "normally". This used to be called having a mental breakdown as reality teared away the curtain on their fantasy.
