"...he supports objective debates about it, as though such a thing were possible, let alone useful."
Maybe a more fair statement is a debate about such a thing could not happen and would be useless within public digital forums like Twitter. To say there is a subject that exists that cannot be debated objectively at all is censorship. Some subjects require a higher curation of debate context than others in order to have a good-faith discussion, this being one of them. If your goal is to maximize the well-being of everyone, then somewhere in the transitive chain truth and understanding would also be your goal. Censorship is the antithesis to truth and understanding.
