It's not exactly a new argument or a disinterested proponent; I think it's OK to take priors into account rather than spending time to address every argument from scratch.
Consider the fact that Quillette (which Lehman helped found explicitly supports allowing free speech for nazis, arguing (in defiance of available facts) that there's no evidence Nazis can radicalize people into being mass shooters. Oddly, they complain about Nazis being treated like ISIS but I don't see them going to bat for ISIS' right to free speech, presumably because there are no doubts about ISIS' use and glorification of violence.
