Whether or not his action was political, their response that insinuates that he is not a true leftist is not only incorrect but irrelevant, though it&#x27;s understandable that somebody in a field where virtue signalling is so critical might think that this is a valid counterargument. Imagine that somebody pointed out that articles in a mathematical journal are incorrect and the editor responds with &quot;yea, but you&#x27;re not a true leftist!!&quot;. Virtue signalling and victimology over arguments, opinion over facts, obscurantism over clarity, etcetera.<p>The claim that people outside of the field have a hard time understanding it has the advantage of being correct when applied to science and mathematics. This is why Sokal&#x27;s book only analyses the use of physics and mathematics in postmodernist literature. Since he is physicist and mathematician the claim that he just doesn&#x27;t understand what he is talking about in his criticism falls flat.<p>I know I&#x27;m being harsh, but ridicule and contempt is the only way to get rid of this before it further infects campuses and, after the current generation of students grows up, politics.
