You'll have noticed on the internet that there's a tendency to prioritise engaging with things you disagree with (hell, half of my HN comments are because I felt motivated to write something to disagree with some OP at some point - even this one).
What that means is the traditional small-c conservative 'village elders', 'parish priests', and 'elected officials', who hold authoritative positions not because they're controversial, but because they historically represented positions of neutrality and consensus end up with quiet megaphones, and the madmen claiming the world is flat and there's a paedophile ring run out of a pizza shop end up with the loudest megaphones.
Half of the population is below average intelligence, and giving the wrong people the loudest megaphones has a devastating effect on society.
