The belief that the perspective of every side of an issue deserves equal—and continual—consideration, most often with the implicit endorsement of there being some validity and/or merit to each, is one of the most damaging developments in society.
Even otherwise intelligent, thoughtful people have been taken in by that nonsense, which has lead to insane and/or malicious people gaining exposure and following that would have likely never happened in previous generations.
Not all perspectives and opinions hold the same validity, nor are all worthy of (especially continual) consideration, for the same reason that you wouldn’t be asking (and intently listening to) random people on the street for their opinion on your cancer diagnosis, or where you should invest your pension, or the best way to build half mile suspension bridge.
One of the biggest downsides to the democratisation of information (which, in isolation, has huge benefits to society, even if they can be destabilising) is the mad belief that everyone’s opinion is equally valid and valuable and therefore should be (repeatedly) platformed. The “free market of ideas” is another tragically flawed theory of information that also fundamentally underestimated (and misunderstand) the new dynamics of socialisation and behaviour that would come with the adoption of the internet.
It has lead us to MAGA, Brexit, the Palestinian Genocide, dictator democracies, and many other horrible movements, events, and situations.
