On the other hand forcing media to give 50% of time/space to "both sides" leads to silly situations like 50% of media saying vaccines do cause autism, dinosaur fossils were planted by the devil, net neutrality is bad, etc.
You could either keep a blanket rule of 50% coverage excempted from such cases, or you could only mandate 50% coverage rules on particular settings/events, such as Presidential election main-line coverage.
