DJT & MAGA are defined by the very thing they told you was "a dangeours leftwing ideology"

Postmodernism is not an ideology. It's an aestherics & sociology research term describing a form on public attitudes expressed in the output from a certain age. Societies don't move through these waves uniformly, and what was the expression for liberal left in the 1980's only started coming into fashion for the right wing in the 2000's. Donald Trump's dictatorship was apparent all the time, and why it appeals to MAGA today is because he exhibits the key defining factor of ironic detachment found in the cultural landscape of the right wing of today. They find his fumbling, incompetence & stupidity a familiar and contemporary container for expressing the values they are aligned with: Far right authoritarianism.
