De Zayas is a registered Republican voter, although he supported Bernie Sanders in 2016. Writing in 2018 in the Canadian magazine "Humanist Perspectives", he warned about the growing radicalism of the Antifa movement in Germany, reminiscent of the Nazi SA of the 1930s: " A new wave of totalitarianism is sweeping through Germany with the collusion of the mainstream media, which ... seldom criticize Antifa" and downplay their anti-democratic violence. On several occasions de Zayas has been invited as an expert before German courts and before the Rechtsausschuss (legal committee) of the German Bundestag, invited by the CDU/CSU.
