There are a lot of parallels between modern America and Germany during the leadup to the Nazi era: growing racism and xenophobia, economic decline, deteriorating democratic institutions, an obsession with militarism, violent political polarization. But the defining factor that the two countries share in their descent into fascism is a decision by each country’s liberals to participate in the campaign to repress the revolutionaries.

Social democrats helped usher in fascism in Germany. They’re doing it again in America.
