Not all viewpoints have equal value. There is a very real difference between disagreeing over how to interpret actual reality (e.g. disagreeing over what is an acceptable level of income inequality in society) and disagreeing over manufactured issues created by feeding lies to people to make them fear for their society because of threats that do not exist. There was no legitimate argument over whether pre-Brexit UK was on the verge of being invaded by Syrian terrorists, whether Obama is an American citizen, or whether there were 'caravans' of migrant-criminals approaching the US-Mexico border. These entire concepts, and the 'polar differences' they created, were entirely fraudulent inventions that Facebook was used to fabricate.
