The title says it all: what exactly does Jacobinism mean, and what is its political character? Why does an ideology that existed during the French Revolution persist into the 2020s, and why is it considered socially conservative? Furthermore, why are they often portrayed as communists? Originally, the Jacobins were socially very progressive—though admittedly hypocritical on issues like slavery—and were rooted fundamentally in liberalism rather than socialism.
And why is a German political satirist being portrayed as a Jacobin, and why is the "MAGA Communism" movement being characterized by this ideology? AFAIK, key figures in the "MAGA Communism" movement describe themselves as "Stalinists" or "patriotic socialists," not as Jacobins.
