Indeed it could. Right-wing idealogy is anti-democratic, anti-constitutional, anti-American. The world over, right-wing movements have been the death of democratic institutions and governments for centuries. Pinochet’s Chile, Mussolini’s Italy, Hitler’s Germany, Franco’s Spain, are only the most famous examples. Look at every right-wing government in the world today, and it is an authoritarian brutal dictatorship at the extreme, or a “velvet gloves over the iron fist” authoritarian government at the least, always promoting austerity, militarization, privatization (read: profitization) of public institutions, marginalization if not outright demonization of minorities and the poor, and every other undemocratic measure possible. Right-wing means evil, period. What is truly scary to me, is the seemingly growing number of people in this country - and the world - who seem to be drawn to this sick, evil ideology. “Only” 30% of Americans love Trump, but that means that almost a THIRD of Americans subscribe to the sick, authoritarian ideal. And the right-wing movements gaining in popularity all over Europe shows similar trends outside this country as well (Le Pen’s National Front in France, Law and Justice in Poland, etc.).
I would be a hypocrite if I said conservatism should be outlawed - we are a “free” country, supposedly, after all. But it bring up the question - when an ideology promotes death, destruction, hatred, alienation, and with an agenda of anti-freedom, anti-constitutionalism that impoverishes millions - when should it be outlawed?
