Talk politics.

Economic planning was the cause of totalitarianism for Hayek, rather than the being just a feature of it.

I would need a citation for this, as I haven't seen this be an argument that Hayek makes.

It's also not really a core piece of the argument against central planning, in my opinion.

That the economic policies the Weimar government had engaged in had led to the election of Hitler was and is obvious to any unbiased observer.

It was more the Great Depression that let to his election more than any particular economic policies of the Weimar government. http://www.germanculture.com.ua/library/history/bl_hitler_rise_of_nazi.htm And you're painting with a wide brush to try and implicate Hayek in the rise of Hitler in order to discredit his economic theories.

Pilkington notes that the toilet seat "is generally the cleanest place in the bathroom and yet it is viewed as a space that arouses disgust and caution in most."

He's missing that it's the cleanest because it arouses disgust and caution and thus is cleaned more often and regularly.

And ascribing the economic success of Germany after Hitler's election solely to Hitler's economic policies is basically crap logic and making the same errors that you're ascribing to Hayek.

You haven't shown any cognitive dissonance here.
