The author might want to admit that 'moderate reasonable' positions are also branded and incentivized, and can lead to lucrative jobs in the corporate media and think tank worlds and even in the social media influencer space.

What really smells bad here is the 'stupid and insane' theme - everyone who disagrees with my moderate position is living in stupid-world or lacks sanity is itself an extremist fundamentalist position held by many so-called centrists and institutional bureaucrats whose impartiality is questionable as they are economic beneficiaries of the status quo.

Relatedly, extremist positions arise from extreme conditions - a well-paid experienced factory employee who loses their job due to the corporation outsourcing manufacturing to India will likely adopt an extreme position of opposition to shareholder or venture capital control of corporate decisions, and start advocating for worker control of corporations. Does that make them stupid and insane? Or is that just the spin the shareholders and venture capitalists are trying to put on their reasonable moderate position about sharing wealth and power in a more democratic fashion?
