Democracies around the world are under attack, as authoritarian leaders sow doubt about the electoral process and discontent with other democratic institutions.

Alexandre De Moraes has ordered the pretrial detention of hundreds of rioters and the suspension of social media counts en masse. Conrado Hubner, a Professor of Constitutional Law at the University of São Paulo, columnist for the newspaper Folha de Sao Paulo, and co-founder of Brazil's Center for the Analysis of Liberty and Authoritarianism, joins us to discuss how far defenders of democracy should go in fighting the far right.
