Luis Fernando "Nando" de Moura Cagnin is a Brazilian musician, music instructor and YouTuber who produces videos about heavy metal culture, video games, and politics. As of 2016, Moura described himself as a conservative, saying that he emphasized preserving the good that society had produced and supporting freedom in individuals' actions. He opposed treating homosexual couples in the same manner as heterosexual ones, arguing that the former could not raise a child effectively and arguing with references to Plato and Aristotle. Moura was a strong supporter of Jair Bolsonaro and campaigned for him in the 2018 presidential election. Later, he started to sharply criticize Bolsonaro's administration, calling him a "traitor" in a 2019 tweet criticizing the sanction of the "judge of guarantees" amendment (not foreseen in the original project of the Anti-Crime Package presented by Minister Sergio Moro). He became one of the main criticizers of Bolsonaro's government because of the government's attitudes about corruption and the COVID-19 crisis.
