Critics of such measures in both countries claim that the will of the people supersedes everything, even if the result would elevate a candidate to a position of power that would enable them to destroy democratic structures from within—and do so using taxpayer money.

Those who had abolished the rule of law and democracy had come to power legally and through democratic processes. A logical conclusion from this was that the laws and constitution of the Weimar Republic had not sufficiently protected democracy and the rule of law. To counter this, a number of protective mechanisms were written into the Basic Law of the Federal Republic. One of these is the possibility of banning political parties.

I also like that they brought up Popper and intolerance and tolerance.

Great article.
