It's hardly a controversial position that the Reign of Terror had virtually nothing to do with the nobility or monarchy, both of which had been abolished by that point; and everything to do with the suppression of political dissent by means of state terror.
The lesson of the Reign of Terror is not "kill the rich". It's not even "kill your enemies". It's "normalizing political violence will inevitably, maybe literally, blow up in your face." People who equate the guillotine and Reign of Terror with successful political violence, or even successful economic and political reform, are not just wrong but dangerously wrong, and need to corrected.
Unpopular opinion: The Windows Registry, a centralized, strongly typed key:value database for application settings, is actually superior to hundreds of individual dotfiles, each one written in its own janky customized DSL, with its own idea of where it should live in the file system, etc.
