Vincent Trémolet de Villers' editorial addresses the recent controversial speech made by Jean-Luc Mélenchon in Lyon, highlighting what he perceives as a troubling trend within France's left-wing political sphere. Mélenchon’s rhetoric, according to de Villers, compromised basic civility and decency, as he reportedly used inflammatory and aggressive language that bordered on antisemitism while scapegoating Jews for various societal issues. The editorial criticizes Mélenchon for promoting a narrative steeped in paranoia and fanaticism, which the author believes could lead to a moral and political suicide for the left in France.

De Villers describes Mélenchon's performance as 'obscene', noting that it replaced nuanced dialogue with base instincts and accusations. He points out Mélenchon's verbal attack on a young man named Quentin, who was mentioned in a violent incident, indicating a lack of accountability from the left for such actions. By denouncing the police and other figures in society while absolving his supporters of any blame, Mélenchon is portrayed as fostering a toxic political atmosphere that could alienate moderate voters and damage the credibility of leftist movements.

Ultimately, the editorial serves as a stern warning to the left in France about the consequences of embracing extremist rhetoric and undermining civil discourse. De Villers implies that if the left, represented by figures like Mélenchon, fails to recalibrate its approach, it risks endangering its future and the moral fabric of its political stance. Through this critique, the author urges the left to reclaim its dignity and responsibility, moving away from scapegoating and divisive speeches that threaten to unravel its foundational principles.
