I don't think facts are subject to a fairness doctrine. You'll find basically every academic in existence saying Trump is a fascist because he is observably so based on statements he and those around him make, and policies he enacted. The question then is how is it not a first amendment violation for the state to prohibit a speaker presenting factual and evidence-based research.
