I suspect the ban is based off of all of the post World War 2 scholarship on fascism and the list of signs and symptoms - when you have literal nazis not facing immediate ejection but being condoned, pushing every all while engaged in such a political shift such that George W Bush would be now considered leftist it is reasonable to be worried. Implying your foes lack even the sapience of a goldfish is /way/ more worrying in that context than the juvenile unself reflective solipsism.
